The online oil particle counter employs the optical blockage (light-blocking) counting principle specified by the International Hydraulic Standards Committee. It is a dedicated device for on-site, online measurement of oil contamination levels. Featuring a compact size, lightweight design, rapid detection speed, high precision, and excellent repeatability, it operates reliably under extreme conditions such as high temperatures and pressures. Suitable for engine oil, gear oil, transformer oil (insulating oil), hydraulic oil, lubricating oil, synthetic oil, water-based fluids (water-based hydraulic oil, water-glycol, etc.), alcohols, ketones, and all other transparent solvents. Widely applicable in aerospace, petrochemical, transportation/port, steel/metallurgy, and automotive manufacturing sectors.
Utilizes the principle of optical blocking (light shielding) with high-precision laser sensors, offering compact size, high accuracy, and stable performance.
Features a built-in data analysis system that displays real-time particle size data for each channel and automatically classifies sample grades.
Suitable for on-site online monitoring, enabling real-time tracking of particle contamination levels in oil systems.
Standard models withstand 100 kg pressure directly; optional pressure reducers support online high-pressure measurement.
Features volume-based and time-based flushing modes for convenient operation and maintenance.
Allows independent setting of customizable alarm levels for contamination or cleanliness detection.
Built-in particle contamination grade standards include ISO4406, NAS1638, SAE4059, GJB420A, GJB420B, ГOCT17216, GB/T14039, and others.
Built-in calibration function supports standards including GB/T21540, ISO4402, ISO11171, and GB/T18854, providing results for all built-in standards in a single test.
Rugged exterior design suitable for demanding work environments.
Supports continuous testing or customizable test interval settings.
Bottom-in, top-out mode minimizes interference from air bubbles in the test results.
Dual Chinese/English interface allows seamless switching, suitable for export markets.
Touchscreen or membrane keypad operation with free switching; instrument interface can remotely control printer power.
Optional 4G/5G module supports remote data monitoring, historical data retrieval, and curve queries via mobile or computer (optional).
Built-in moisture and temperature sensor module simultaneously outputs four parameter readings (optional).
Extensive storage capacity with options for internal instrument storage or external storage devices.
