The HI 96831 Ethylene Glycol Digital Refractometer is a rugged, portable, water resistant device that utilizes the measurement of refractive index to determine the percent volume and freezing point of ethylene glycol based solutions.
This digital refractometer eliminates the uncertainty associated with mechanical refractometers. HI 96831 samples are measured after a simple user calibration with distilled or deionized water. Within seconds, the refractive index and temperature are measured and converted into one of two measurement units; % volume or freezing point. These meters use internationally recognized references for unit conversion and temperature compensation for glycol solutions (e.g. CRC Handbook of Chemistry and Physics, 87th Edition).
