User questions & answers

Question:	My refractometer is impossible to calibrate... anybody else have issues or tips
Answer:	I used distilled water and put three drops on the prism. Close it so there is no air bubbles and right under the light it should have a blue tint to it. Just lining the Blue tint line to the 0 line.
Question:	does it measure brix for grape to know if it is ready to harvest for wine
Answer:	Yes it does. I've tested boxes of (Zinfandel) grapes from California in September that I use for wine-making and they've been in the neighborhood of 23-25 brix. I'm sure you can read about higher brix levels but that's about what I get for those grapes and this device. All you do is squeeze a drop or two onto the sloped lens, close the clear cover over so it smears, hold it up to the light and read the scale. You can try several grapes or crush a number of them together to get an average.
Question:	can I use this for melases ? and how to use
Answer:	I am assuming the by melases you mean molasses. I have not tried to measure the specific gravity (SG) of molasses but I suspect you will have trouble with pure molasses. The SG might be out of range and the dark color of molasses may make it hard to read. If the molasses is dissolved in water then yes you should be able to use the reflectometer. To use a refractometer first zero the refractometer using plan water close to the same temperature as what you are measuring. SG is dependent on temperature. Once zeroed dry the surface and put a couple of drops of what you want to measure on the refractometer and read the results. The refractometer is easier to read in bright light: sunlight or a flashlight.
Question:	Can i use this to test the sugar content of my homegrown fruits and vegetables
Answer:	Yes, you can.

User questions & answers

Question:	Can this be used to measure the alcohol content of homemade hand sanitizer
Answer:	Yes, this tool just measured the Specific Gravity/Brix of a liquid. If you know what the beginning SG/Brix was , and then measure the "after fermentation" SG/Brix , you can figure out what the Alcohol content is in a liquid. It will not just tell you what the Alcohol Percentage is in a wine though. You will have to know the two values and do the math
Question:	Will this measure alcohol content of finished beer? I'm making an "NA" and want to be sure that it's truly non-alcoholic...or at least less than
Answer:	As i know, this device measures the sugar content of a clear and nonalcoholic solution. It doesn't measures the alcohol content, but the alcohol potential (after fermentation) of a water and sugar solution.
Question:	Can I use this to check the dilution of isopropyl alcohol to make sure it’s at
Answer:	The liquid measurement is very easy. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look throught the eyepiece against the light (focus, if necessary) and you will be able to read the result value on the scale.

Answer:	It does not. you use the included eye dropper to put a small sample of fluid on the lens and close the lid. It displays the specific gravity of the fluid in various units as illustrated in the image.
Question:	Instructions with tester says not to measure corrosive chemicals. Last time i checked battery acid is very corosive. what is the answer
Answer:	I'm sorry the instructions may be a little confusing. The instrument can be measured acidic and alkaline and other general corrosive liquid. But we do not recommend keep these liquids on the instrument for a long time. The residue should be cleaned immediately after measurement.
Question:	Does this kit has guidance on which specs is required as a general information to be used? Or where should I find that information
Answer:	That info is marked on the scale. For lead-acid batteries it has along side the scale, recharge, fair and charged. The antifreeze is marked in Celsius for freeze point and the DEF scale is mark from 30-35 with 32.5 being the normal recommended concentration. Disclaimer: That's the way mine came marked but no specs listed on instructions.
Question:	How accurate is this for testing DEF
Answer:	Accurate as long as you set to zero with distilled water first.
