ATC Beer Wort Brewing Wine Refractometers 0-32% Brix SG Wort Specific Gravity 1.000-1.130 Protable Beer Refractometer With Box Description: refractometer measures the Brix and Specific Gravity of your Wort or wine. Measures Brix: 0-32% and Specific Gravity:1.000-1.120ATC (Automatic Temperature Compensation) for accurate readings.A refractometer is easier and more accurate than a hydrometer for measuring sugars.This refractometer is for measuring the sugar content of beer and includes an automatic temperature compensation of 10 - 30 degree Celsius. This refractometer can replace your hydrometer for easier and more accurate measurements. Simply use the dropper to take a sample of wort and put it on the prism. Then hold the refractometer up to the light and look through the eyepiece. Due to the dual scale there is no need convert to specific gravity as the scale measures both Brix and SG How to Use: 1. Align the Cover Plate with light, adjust the Focus Adjustment until you see the scale clearly. 2. Calibration: Accurate Measurement depends on careful calibration. Please make sure the ambient temperature is about 68 F, distilled water can be used to calibrate. Open the Cover plate. place 2-3 drops of the distilled water on the prism, then close the cover plate and make sure the water spread aro the prism without any air bubbles or dry spots. wait for about 30 seconds to let the reading to stabilize. Look into eyepiece and turn the calibration screw with the screw driver until the reading is "0" 3. Clean the prism with 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 the water spread aro the prism without any air bubbles or dry spots. wait for about 30 seconds to let the reading to stabilize. Align the prism aembly with the light source. look into eyepiece and you can get the reading. Features: With Built-in ATC compensation Range (Automatic Temperature Compensation) from 10C to 30C For field use, without having to re-calibrate after changes in ambient working temperature. Soft rubber eye piece for comfortable viewing Equipped with scale measurement which provides direct reading Accurate testing results guaranteed Extremely easy-to-use and calibrate Durable and built to last long Adjustable manual focusing Uses ambient light only which means battery or power source is not required.
