Visual particle monitor

The OPM II is a visual particle monitor that measures the the level of contamination and the purity trend of non-aggressive fluids based on the light-extinction principle. In operation, a laser radiates through the measuring cell, directed against a photo diode. As fluid particles pass through the laser beam, the reflected light is reduced and recorded accordingly. Due to the continuous purity monitoring, changes in a system are quickly identified and consequential damage can be avoided.


  • Can be integrated into external systems, or operated independently
  • Results can be transferred to a PC for better analysis
  • Fluid cleanliness class is optionally displayed according to ISO 4406:99 or SAE AS4059E
  • Temperature is measured via electronic circuit board
  • Includes “operating hours” counter, that restarts counting at the last stored time before any interruption
