The Online Oil Contamination Monitor is a device specifically designed for detecting particle contamination levels in liquids. It employs the optical blockage (light-blocking) counting principle established by the International Hydraulic Standards Committee and is developed in accordance with national and international standards such as GB/T 18854-2002 (ISO 11171-1999).
It delivers rapid, precise, reliable, and repeatable test results. With simple and convenient operation, it is suitable for online monitoring in various oil systems. Two or more slave units can be connected to a single host or platform for comparative testing, offering straightforward operation and flexible configuration options. The Online Oil Contamination Monitor finds extensive application across aviation, aerospace, power generation, petroleum, chemical processing, transportation, port operations, metallurgy, water treatment, machinery, and automotive manufacturing sectors.
Employs the specific optical resistance (light-blocking) counting principle established by the International Hydraulic Standards Committee.
High-precision laser sensor with wide testing range, stable performance, low noise, and high resolution.
High-strength metal housing suitable for harsh environments such as field applications.
Features a high-precision dual-plunger pump for stable injection speed and high sampling accuracy.
Supports standalone operation, upstream/downstream integration for filtration rate calculation, multi-unit networking with centralized remote monitoring, and versatile functions including curve generation, historical data queries, and data export. Its adaptable configurations enable broad application scenarios.
