The HI 96832 Propylene 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 propylene glycol based solutions.
This digital refractometer eliminates the uncertainty associated with mechanical refractometers. HI 96832 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. This meter uses internationally recognized references for unit conversion and temperature compensation for glycol solutions (e.g. CRC Handbook of Chemistry and Physics, 87th Edition).
HI 96832 is supplied with battery and instruction manual.
