Features：With Built-in ATC compensation Range (Automatic Temperature Compensation) from 10°C to 30°CFor field use, without having to re-calibrate after changes in ambient working temperature.Soft rubber eye piece for comfortable viewingEquipped with scale measurement which provides direct readingAccurate testing results guaranteedExtremely easy-to-use and calibrateDurable and built to last longAdjustable manual focusingUses ambient light only which means battery or power source is not required.Cushioned with soft & comfortable non-slip rubberSpecification：Reference Temperature: 20°CATC(Automatic Temperature Compensation) Compensation Range: 10°C~30°C (50°F~86°F)Manual calibration with mini-screw driver provided 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.A. 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 aross 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 aross the prism without any air bubbles or dry spots. wait for about 30 seconds to let the reading to stabilize. Align the prism assembly with the light source. look into eyepiece and you can get the reading.4. Please leep the refractometer dry and clean in the box, which can make sure the reading accuracy and durable.
