Refractometer removal 0-80% of alcohol concentration test alcohol liquor concentration Meter, rice wine concentration test and used to detect alcohol content of liquor, The alcohol refractometer (liquor) series is specifically detects the concentration of Ethanol in the aqueous solution, the most intuitive instrument, can quickly determine the percentage concentration of alcohol (ethanol).
This Refractometer model Works for alcohol testing (to test the alcohol concentration in the Alcohol Solution, not grape wines or other fruit wines). Its unit is w / w (weight / weight), the working temperature of the refractometers is suggested at 20 ° c (about 18 ° C to 25 ° c).
Measure alcohol content accurately in seconds! All you need to do is make Distillate of the liquids to be measured and then place the distilled sample in the Prisma.
Many of the refractometers on the market are made of plastic. However, people who work with alcoholic drinks or industrial fluids on a regular basis believe that the metal refractometers provide more accurate measurements and that they simply stand up better over time and provide you with fast and accurate results – the same characteristics with all of our refractometers.

How to use:

1. align the cover plate with light, adjust the focus adjustment until you see the scale clearly.
2. calibration: exact measurement depends on careful calibration. Make sure that the room temperature is around 68 ° C, distilled water can be used to calibrate.
Open the cover plate. Place 2-3 drops of distilled water in the prism, then close the cover plate and make sure the water spreads aross the prism without any air bubbles or dry stains. Wait about 30 seconds to let the reading stabilize. Look into the eyepiece and turn the calibration screw with the screw driver until the reading is “0”
3. clean the prism with a soft cloth, then place 2-3 drops of the liquid sample to be tested on the prism. then close the cover plate and make sure that the water has spread aross the prism without any air bubbles or dry stains. Wait about 30 seconds to let the reading stabilize. Align the prism assembly with the light source. Look into the eyepiece and you can get the reading.
