HI 96832 Propylene Glycol Digital Refractometers is a rugged, portable, water resistant devices that utilize the measurement of refractive index to determine the percent volume and freezing point of propylene glycol based solution. These digital refractometers eliminate mechanical refractometer uncertainty. HI 96832 sample is 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.
HI 96832 utilize internationally recognized references for unit conversion and temperature compensation for glycol solutions (e.g. CRC Handbook of Chemistry and Physics, 87th Edition).
