Atago PAL-102S Cutting Oil Refractometer – Industrial Concentration Meter

The PAL-102S is a digital refractometer designed for rapid and accurate measurement of cutting fluid, hydraulic oil, and cleaning solution concentration in metal working and CNC production environments. It enables instant quality control at the machine or production line without requiring laboratory analysis.

Proper fluid concentration is critical for tool life, machining quality, and cost control. Low concentration results in insufficient cooling and lubrication, while excessive concentration increases unnecessary costs and waste generation. The PAL-102S delivers results with 0.1% resolution in approximately 3 seconds using only 2-3 drops of sample.

The water-floating feature reduces risk of loss if the device falls into coolant; IP65 protection rating ensures durability against industrial environments including chips, splashing, and moisture. The wide automatic temperature compensation range (10-100°C) maintains measurement consistency across factory environment temperature variations.
