PAL-88S Refractometer – Propylene Glycol Concentration Measurement

The PAL-88S is a handheld, portable refractometer designed to measure propylene glycol concentration from 0.0 to 90.0% (V/V) and freezing point from 0 to -60°C. It offers automatic temperature compensation (ATC) and an LED display with ELI technology for accurate readings in varying light conditions. With a robust ABS housing and IP-65 rating, it is water-resistant and durable. The metal sides of the sample well ensure fast temperature adaptation and the sloped design prevents spills. The device comes with a protective plastic case and is easy to calibrate with tap water. Ideal for precise refrigerant measurements in industrial and laboratory applications.
