Atago PAL-88S Digital Propylene Glycol & Antifreeze Refractometer

The Atago PAL-88S is a professional-grade digital handheld refractometer specifically engineered to monitor the concentration and freezing point of Propylene Glycol solutions. Due to its non-toxic nature, propylene glycol is the standard coolant for food and beverage processing plants, solar thermal systems, and large-scale HVAC units. The PAL-88S provides meticulous data by displaying both the volumetric concentration (% V/V) and the freezing point from 0 to -50°C in just 3 seconds, ensuring optimal system protection against extreme temperatures.

Designed for durability and ease of maintenance, the PAL-88S is IP65 rated, making it completely water-resistant and safe to rinse under running water. Its advanced Automatic Temperature Compensation (ATC) ensures consistent accuracy within a 10°C to 40°C range, eliminating errors caused by fluctuating environmental conditions. Requiring only a minimal 0.6 mL sample and powered by two AAA batteries—offering up to 11,000 measurements—the Atago PAL-88S delivers laboratory-grade precision in a rugged, pocket-sized format, making it an essential tool for professional industrial maintenance and coolant diagnostics.
