10 best refrigerated coolers

A refractometer for aquariums is a specialized tool used by aquarium enthusiasts and professionals to measure the salinity or specific gravity of the water in their aquariums.This device is crucial for maintaining the optimal conditions for marine and reef ecosystems within the aquarium.

Key features and information about refractometers for aquariums include:

  1. Principle of Operation: Refractometers work based on the principle of measuring the bending of light as it passes through a liquid. In the context of aquariums, they measure the refractive index of the water, which is directly related to the water's salinity or specific gravity.

  2. Measurement Units: Refractometers can display readings in various units, including parts per thousand (ppt), practical salinity units (PSU), and specific gravity (SG). The choice of unit depends on the preferences of the aquarist and the specific needs of the aquarium inhabitants.

  3. Calibration: It's essential to calibrate the refractometer regularly using a calibration solution or a known standard to ensure accurate readings. Many refractometers come with calibration solutions or guidelines.

  4. Types of Refractometers: There are two main types of refractometers for aquarium use:

    • Analog Refractometers: These have a built-in analog scale where you read the measurement directly through an eyepiece.
    • Digital Refractometers: These provide digital readings on an easy-to-read screen, often with additional features like temperature compensation.
  5. Temperature Compensation: Some advanced refractometers for aquariums have temperature compensation features. Since water temperature can affect the accuracy of salinity measurements, these devices automatically adjust the reading based on the water temperature.

  6. Maintenance: Regular maintenance includes cleaning the refractometer's prism or lens to ensure accurate readings. Most manufacturers provide guidelines on how to clean and care for their specific models.

  7. Application: Aquarium hobbyists use refractometers to monitor and maintain the proper salinity levels for their marine and reef aquariums. Different species of fish and coral have specific salinity requirements, and accurate measurements are vital to their health and well-being.

  8. Availability: Refractometers for aquariums are widely available through aquarium supply stores, online retailers, and specialty scientific instrument suppliers.

In summary, a refractometer for aquariums is a valuable tool for maintaining the ideal salinity levels in marine and reef aquariums. It allows aquarists to monitor and adjust the water conditions to ensure the health and vitality of their aquatic inhabitants. Regular calibration and maintenance are essential to ensure accurate readings and the overall success of the aquarium.

User questions & answers

Question: Do you think this is a better cooler than the Coleman cooler for a truck driver? I'm looking at this one or the Igloo one
Answer: Read my review of the Coleman Hot/Cold 40 Qt. Had a Coleman from 2000 that finally died due to a design flaw that allowed the fan to bind in the nacelle/ housing. Bought a new one that lasted 10 weeks. Finally got my refund 4 months later. Can't compare it to this one, but some of the other answers here are misleading. This product is not a portable refrigerator. Those have thermostats and use a compressor. Peltier devices are power hogs - about 5% efficient at transferring heat. So, 95% of the heat you feel on the exhaust of these is produced by the Peltier device, not from inside the cooler. Also, some heat is transferred through inefficient insulation. That's why it takes hours to remove heat from the interior of these coolers before you can start using them.
Question: Does this actually cool to 40 degrees or does it cool to 40 degrees below ambient temperature? That is a huge difference it gets to 100 where I live
Answer: We used it while traveling out west last August where temps were in the 100's and it kept everything really cold.
Question: ft cord is not long enough to reach the back of my minivan, will cooler work properly with a dc cord extension? Is it quiet enough to sleep next to
Answer: I believe it should work with a DC cord extension. We had the cool in our hotel rooms while traveling and had no problems with it being noisy.
Question: How long will it stay cold when not powered
Answer: If powered long enough to get to its maximum temperature of 38F and turned off it will stay cool for approximately 24 hours. By way of a couple of specific examples: (a) I’ve placed a bag of ice in this cooler when it was at its peak cool temp of 38F, turned the cooler in off, and had the ice stay frozen (without ANY liquid water forming) for 6-10 hours depending upon the outside temp, and (b) I’ve placed a bag

Food and beverages for a picnic, a barbeque, long road trips, wilderness adventures, or overnight camping trips can now remain heated or cooled throughout your trip.

User questions & answers

Question: How long is the provided power cord that goes in the 12V receptacle? Can you purchase a longer one if needed
Answer: About 90 inches to the end of the 12V plug (the plug itself is about 4 inches, so I'd subtract that from the distance the cooler can be from the receptacle). I did not look for a longer one, but I did purchase an adapter that would allow you to plug into a standard 120V outlet. The end that goes into the cooler is hardwired, so you couldn't replace it but I'll bet you could by an adapter to extend it.
Question: Is it tall enough for milk gallons or 2 liter bottles to stand upright
Answer: Yes 2 gallons standing and I put 4 lbs of ice just in case, but the ice did not melt
Question: Can you tell me what power sources this cooler can connect to out of the box? 12 Volt DC? 120 Volt AC? Both
Answer: As of 2019, I only received the 12 volt plug that goes into the cigarette lighter. I saw more people saying that they received both compared to those only receiving the 12V which comes attached to the cooler. I had to buy the 120 volt cord as I will need that to plug into my solar as my 12 volt power sources do not work.
Question: The stated product dimensions are 24 x 17.2 x 16 inches. Is that L x W x H or H x L x W, etc.? Just want to know if it will fit in the trunk of my Camry
Answer: It doesn't matter - you can use the cooler either standing up, like a fridge, in which case the dimensions are 24"tall x 16"wide x 17.25deep, or use it laying down, like an ice chest, in which the dimensions are 17.25"tall x 24"long x 16"wide

Coleman Company History

W.C. Coleman could see the light for the darkness. The young salesman was taking a stroll after a hard day’s work selling typewriters, and spotted a new type of lamplight in a drugstore window in Brockton, Alabama. This new light burned with a strong, steady white flame and was fueled by gasoline. The standard lamp of the era burned kerosene and produced a smoky, flickering, yellowish light. W.C. was stricken with very poor eyesight, and was very interested in this new, steady white light that enabled him to read even the smallest print in books and on medicine bottles. Coleman saw potential in the new light, and through his vision a new company was born that would put America’s farms and ranches in a new light, and would eventually make his name synonymous with outdoor fun.

User questions & answers

Question: Is it ok to put dry ice in it to maintain colder temperature
Answer: Yes
Question: Will it work if it gets rained on
Answer: This is a guess but since the exhaust fan is on the lid along with the cords, I wouldn’t want water getting in and pooling around these connections. I might be wrong but I wouldn’t take the a chance if doing damage.
Question: Will it drain my battery in my car
Answer: I have only used it briefly in my car while driving to and from places and it was fine. I use it mostly as my refrigerator at home since mine blew out months ago and I had been using a styrofoam one while awaiting a new refrigerator until this arrived not long ago and I love having cold things now! The ice in the cooler just didn't do the trick every day for over 3 months until I got this! Granted my cold food storage is extremely limited with this small size and it's not for frozen foods or ice only cold items or you can switch to warm also. I like the entire concept! But I would never recommend leaving any electrical plug in item in a vehicle while unattended and the car is not running unless you read your manual for your car. Why? Because I learned the hard way that with my car something as simple as leaving the door and trunk open with the car not running drained the battery! Which seemed like it should not drain a battery but my car said that it would overload the battery if the car was not running so I had to have my battery jumped. Nothing was wrong with my batter it was made that way and the manual stated so which I never read the manual but I know better now and I try to always read the manual for things! Also, I do know that many car batteries and alternators both could possibly be drained by any item plugged in and left running in a car with the motor shut off. There again it depends on if the car were able to generate separately the power to do that if the car were cut off since many are not able. So please be sure to read your car manual to be sure about anything you plug into your car and then you'll know for sure how your car's battery is supposed to function normally with something like this! You'll love the cooler and the warmer both however you choose to use it! Take care!
Question: I want to use this at home and charging everyday to maintain room temperature for my vitamins since I live in a very hot apartment. Is this okay
Answer: I have been using this every day since I received it as a refrigerator since I don't have one. I live in a hot area and had been using a styrofoam cooler and buying ice each day for months which was not the best answer. I will let you know that there is no way to adjust the temperature on this model. It is preset and the fan/cooling and heating unit is at the top inside the cover. Your vitamins would not be maintained at room temperature. This is a cooler or a warmer. Now it is recommended in their directions as an option I believe for maintaining medications at cool temperatures. So if that is an option for you then you may wish to consider it otherwise you may wish to consider something that has a controllable temperature setting. I hope that you find the correct storage!

User questions & answers

Question: From what I see in the reviews it seems that there is a problem with the cord getting to hot and the tip of it melting.Is there a better quality cord
Answer: I've had no issues with the cord attached to the cooler itself but I did have an issue with the Schumacher PC-6 120AC to 6A 12V DC Power Converter that I purchased for indoor use. It ran hot and in less than 6 months it died (Amazon graciously allowed me to return it and gave me a full refund). I replaced it with a Wagan 5 Amp AC to 12V DC Power Adapter. While it gets a little warm, it runs much cooler than with the Schumacher adapter. In fact, the Igloo runs quieter and appears to be more efficient with this adapter. That said I think the power source may be the root cause of the issues that others may have with overheating/melting. I run my cooler inside, all day, everyday as it serves as my office refrigerator and I've had it since last November. I love it and will buy another on the sad day planned obsolescence kicks in.
Question: Why is the larger unit cheaper than the smaller unit
Answer: Really don't know but I found out that the larger one keeps cooler much longer and at a lower degree.
Question: What is the power consumption in amps? I'm useing deep cycle batteries, and low amps is a must
Answer: Working current, battery consumption is between 3.5 to 4.8 Amps according to the owner's operating manual. The current draw is 6 amps maximum at 12-volt DC. I hope this is helpful.
Question: What is the inside height with the lid closed? Looking to keep some Smartwater bottles in there (they are 12" tall and 3" diameter). Thanks in advance
Answer: I have the same question except I'm wondering if the lid will close with 2-litre soda bottles standing inside. That 13 1/2" height measurment sounds rreeaalllly close to the height of a 2 litre bottle. Has anyone actually tried it?

User questions & answers

Question: Would this keep drinks cold on an outdoor patio
Answer: This unit will keep things about 20 degrees cooler than the outside temp at best. I freeze a couple of water bottles or a freezer pack and it will keep things cold much better. Takes about 10 hrs or more before the frozen bottles melt enough to drink with the outside temp at over 90 degrees.
Question: What mechanism generates the cool
Answer: 40 Quart PowerChill Hot/Cold Thermoelectric Cooler Take some cold drinks on your next road trip while leaving the ice at home with a Coleman 40 Quart PowerChill Thermoelectric Cooler. More than a cooler, but not quite a refrigerator, it cools up to 40 °F below the surrounding temperature without any ice. So if you use your cooler in an environment where the temperature is 70 °F, this cooler will maintain an internal temperature around 30 °F. You can use it like you would any other cooler except, instead of throwing ice inside, you simply plug in the 12V car power adapter. Then add your pre-chilled drinks and snacks. Your cooler will reach maximum coldness in about three hours (you can speed this up by adding Coleman ice substitutes) and stay cold as long as it's plugged in. Large enough to hold 44 cans, you'll have plenty of space for refreshments for the whole trip, and you can keep all your contents organized with the storage tray.
Question: Can it be powered with a battery
Answer: Sure....It is 12 volt, so it can be powered with the included cigarette lighter cord, or from any 12 volt battery with the appropriate cord for connection.
Question: How long can it stay plugged in before draining battery
Answer: That question depends totally on your battery supply. Mine runs off of 2 -12V batteries and I can leave it on for 12 hrs or more before I have to start the truck and make sure the batteries don't get past half used.

User questions & answers

Question: Will it fit behind the third row in a Ford Expedition? The dimensions are very close
Answer: It fits behind the seat of our 2010 ford expedition perfectly. Ours is not the EL Expedition.
Question: can I keep an ice pack in it to make it colder
Answer: You shouldnt need to if it is plugged in, but if you do add an ice pack, keep it on the bottom away from the top fan. Having used this to store cold/frozen products before, if the frozen products are near the fan, it can temporarily freeze up.
Question: The dimensions in the Description are different from the dimensions in the photo. Which are the correct dimensions
Answer: Without getting into fractions of inches, the dimensions are: Interior - 13" W(ide) x 9" D(eep) x 13" H(igh). Exterior - 15" W (N/I the handle) x 12" D x 17" H. And this cooler works great!
