Product Description


The HI96832 portable refractometer utilizes the measurement of refractive index to determine the percent volume and freezing points of propylene glycol based solutions. The instrument converts the refractive index of a sample to percent volume or freezing point. These conversions are based on internationally recognized references for unit conversion and temperature compensation for glycol solutions (e.g. CRC Handbook of Chemistry and Physics, 87th Edition). The HI96832 is an easy to use tool for for measuring freezing point and percent volume in propylene glycol solutions, on the production floor or in the lab.
