User questions & answers

Question:	What is the factory margin of error
Answer:	Yes it can. Salinity and temperature. Does a great job of both.
Question:	Is this accurate when mixing salt and setting your salinity for water change. Iv heard can be off a little when hadn't been mixed that long
Answer:	Yes, mine is always off -.002 compared to refractometers. All devices calibrated. Talk to Hanna support and was told it won’t match a refractometer lol. I like it because it’s fast and easy, if I want my water at 1.026, I just make sure the Hanna reads 1.023 I guess others haven’t had this problem but I do, or the others don’t know their salt mix is high
Question:	Can this be used to measure salinity of saltwater fish tank aquarium? Thanks
Answer:	2 inches
Question:	Have you tested the device against another? Inaccurate compared to calibrated refractometer
Answer:	Two AAA batteries

User questions & answers

Question:	Can I use this to check the ec/ph in a soil solution
Answer:	If damaged or isnt calibrating correctly. Unsure on longevity.
Question:	for weekly use, How frequently does the probe need to be replaced
Answer:	Yes. This unit has Auto Temperature Compensation from 0 to 50˚C
Question:	How often should I change the probe
Answer:	I don't know what the "factory" would say their margin of error is, but it's not uncommon for people to check this against a calibrated refractometer and find that it reads 0.002 low. In my saltwater tank, when my refractometer says 1.025, this checker will read 1.023. It's very handy and easy to use, plus confirms my tank temperature, so I use it often, realizing it won't read the same as my refractometer. I don't know or care which one is actually correct, the tank is fine at whatever level this actually is.
Question:	Does this unit have auto temp. compensation (atc
Answer:	You still want to wait for suspended salt to dissolve, salt goes though a chemical reaction while it’s mixing with water and during that reaction it’s harmful to any aquatic life in contact. So wait till it’s fully dissolved, example if I put 1 cup of my mix in 2 gallons of water mix it up and than test while salt isn’t dissolved I’ll get a reading of 17PPT, if I wait 10min while the power head stirs it up longer as it dissolves at 75f the salinity reading changes to close to 35PPT ether 1-2 ppt over depending kn how much salt I added. Ie how much unser a cup or slightly over a cup. Temperature plays a key role to, warmer water can hold more salt

Answer:	We sell typically sell our 250 ml bottle of AccuBrate to calibrate a hydrometer. If you click on our 250 ml bottle description you will see information about calibrating a hydrometer. The exact steps are on the back of our 250 ml bottle. Basically you shake the AccuBrate, rinse the hydrometer, slowly pour AccuBrate into the hydrometer to avoid bubbles, gently tap the hydrometer to release any bubbles attached to the swingarm. Now read the hydrometer. The salinity should read 1.026. If it reads 1.024 then you know your hydrometer is off by .002. Since there is no way to calibrate a hydrometer you just add .002 to whatever your salinity is when you test your aquarium. - Lexi M at Aquatic Experts
Question:	Can I use this calibration liquid on a refractometer use for measuring gravity/brix on wort and beer
Answer:	It’s for salinity
Question:	Can i use this to calibrate my tds meter also
Answer:	No to cailbrate tds I use General Hydroponics use electronic meter reference solutions You can get it here.
Question:	So after calibrating using this fluid, my refractometer show 1.022, hydrometer shows 1.024, what does that mean
Answer:	Since your reading is at 1.022 you need to re-calibrate your refractometer. It is best to follow the operations manual that came with your refractometer or if you can find your model's manual online. If you do not have a manual here is how I calibrate my refractometer. 1. Make sure your glass prism slide and cover flap are clean. Use distilled water when cleaning. Use a soft clean cloth to completely dry glass prism and cover flap. 2. Add 2 to 3 drops of fluid on your refractometer's prism slide and let it sit for about 60 seconds. This allows the sample to adjust to the temperature of your refractometer. 3. Look into the eyepiece and turn the Calibration Screw with your small screw driver that came with your refractometer. The calibration screw is typically located on the top of the refractometer. Slightly turn the screw until the scale reads 1.026 or 35 ppt 4. Your refractometer is now calibrated and ready to test your aquarium. Your hydrometer reading 1.024 means it is reading a few points low. We typically take a black sharpie and write on our hydrometer plus .002. We just add this to whatever our hydrometer's swing arm points to. When it reads 1.022 we know to add .002 to the reading to get an accurate measurement. Best regards, Laurren at Aquatic Experts

User questions & answers

Question:	Unit doesn’t stay calibrated any more still under 1 year how can I get replacement
Answer:	Suction tube will be fine if it's a freshly opened bottle
Question:	Is the eyepiece adjustable to allow you to focus on the values you're looking at
Answer:	First, you would have to define “easily readable”. I have terrible eyesight and bifocals. I need my son to read the numbers because they are so tiny through the eyepiece. It measures quiet accurately and is the gold standard for saltwater aquariums. However, I don’t know if it would work quite as well on a ppt scale. The device measures in specific gravity numbers and ppt. It does read to 0 on the ppt side, but I can’t be sure if it will be that specific for you. You may want to start with the cheaper hydrometer or a more expensive electronic reader. Check out WikiHow’s How to measure salinity. It gives directions on 3 different ways.
Question:	Is suction tube long enough or I need to buy wine thief as well
Answer:	I have had the same problem and you can calibrate it with distilled water, but mine was still off by 2ppm regardless.
Question:	Hoping to test salt level in a fresh water pond which requires 5 ppt, would this be easily readable with this device
Answer:	I don't understand your question - can you re-phrase it?

Dual Scale

The scale range of this refractometer is 0~100‰ and the corresponding specific gravity range 1.000 to 1.070. These are the most common units to show salinity of water.

With this refractometer you can get the result in two different ways at the same time in just one test.

The min reading resolution is 1 ‰, this make it possible to mearsure low concentrated salt solutions.

( 1‰=1 PPT=1000PPM, PPT means"parts per thousand", PPM means"parts per million")

1

Calibration: Place a few drops of distilled water on the prism and use the screwdriver to adjust the calibration screw untill the reading is"0".

2

After calibration, place a few drops of solution you want to test on the prism.

3

Close the daylight plate and hold it under a light source, then look through the eyepiece, you can get the reading.

4

Clean the instrument with a soft cloth after use, and put it into the storage case.
