The Oil Particle Contamination Analyzer measures particle size distribution and contamination class in oils using the light-blocking (extinction) principle. Suitable for testing hydraulic oil, lubricating oil, fire-resistant fluid, insulating oil, turbine oil, and other fluids, this instrument delivers rapid, accurate, reliable, and repeatable test results with comprehensive contamination monitoring and analysis reports.

Widely used in aviation, aerospace, electric power, petroleum, chemicals, transportation, port operations, metallurgy, machinery manufacturing, and automotive production.
