Particle Pal PPM - particulate & water content in PPM

Particle Pal PPM - particulate & water content in PPM

Real time measurement and display of particulate to ISO/NAS/SAE standards as well as water PPM levels in fuels and oils.

We have further developed the award winning Particle Pal by integrating a water monitor that displays water content as PPM (parts per Million) for both oils and fuels.

By incorporating the WMS500 water sensor into the compact design, you can now get instant water content levels for accurate, repeatable measurement of parts per million (ppm). 



Why is water level measurement so important?

Most oils and fuels 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.
With diesel, the maximum allowable water content level is 200ppm. When high water content is present, a series of problems may occur:

  • Fuel Oxidation

  • Formation of paraffin and asphalt long chain polymers
  • Microbial growth and associated contamination
  • Additive depletion

  • Acid formations

  • Gel Formations


The Particle Pal is a self contained field kit with an integrated pump and rechargeable battery. Giving live readings of both solid contamination and water content can rapidly help determine if oils or fuels are fit for purpose.

It can be used in a range of applications and industries including mining, rail, construction, hydraulic and mechanical presses, emergency standby generation, bulk fuel storage, tank cleaning, fuel polishing, marine and many more.
