Laser particle counters

Filtertechnik have developed a portfolio of products for accurate real-time monitoring of Particulate, Water Content and Remaining Life for Oil and diesel fuels.

PC9001: On-line laser Particle Counter

At the heart of our laser counting equipment is the PC9001 instrument. Utilising the exact same laser particle counting technology found in more expensive laboratory particle counting equipment, the PC9001 gives live readings of ISO, NAS or SAE readings. It is rated for continual use in industrial applications and is the ideal monitor to flag sudden changes in an oil condition. Accuracy is +/- half an ISO code.

Particle Pal Range

The PC9001’s incredible technology is built into our range of portable particle monitors, manufactured in Nottingham, the range is detailed below and have a much improved feature set:
