New Particle Pal FS9V2-RH and FS9V2-RH-HP (High Pressure Version)

FS9V2-RH Real-time measurement and display of particulate and water as %RH (% Saturation)

We have further developed the award-winning Particle Pal by integrating a water sensor that displays the percent saturation or relative humidity (RH) in real-time.

By incorporating a state of the art water sensor into the FS9V2 compact design, you can now get instant water %saturation levels for accurate, repeatable measurement as well as the same features the new FS9V2 Particle Pal offers; ISO/NAS/SAE readouts of particulate cleanliness, memory, priming features etc.

Why is water level measurement so important?

Most oils have a maximum allowable water content level. When water levels exceed this value, whether as emulsified, entrained or free water, moisture-related problems are inevitable. Rapid oxidation, depletion of the additive package and rusting of internal components are just a few of the many issues that water in oils causes.

FS9V2-RH-HP (High-Pressure option)

The HP version of the new Particle Pal allows you to connect to a live hydraulic or lube system up to 350 Bar. The reducer valve allows oil to flow into the Particle Pal at 2 Bar.
