The Liquid Cleanliness Tester employs the light-blocking (opacity) counting principle specified by the International Hydraulic Standards Committee. It is a rapid testing device for determining oil contamination levels in laboratories or field settings. It offers advantages such as compact size, lightweight design, fast testing speed, high accuracy, and low cost. Equipped with built-in moisture and temperature sensors, it simultaneously measures water content and oil temperature during contamination testing. Suitable for transformer oil (insulating oil), hydraulic oil, lubricating oil, synthetic oil, and other fluids, it finds extensive application in aerospace, petrochemical, transportation/port, steel/metallurgy, automotive manufacturing, and related industries.
Utilizes the photoresist (light-blocking) principle with high-precision laser sensors, offering compact size, high accuracy, and stable performance.
Features a built-in data analysis system that automatically classifies sample grades based on standards, with automatic data processing and printing capabilities.
Supports external pressure chambers to generate positive/negative pressure, enabling testing of high-viscosity samples and sample degassing.
Includes an integrated data analysis system that displays real-time particle size data for each channel and automatically determines sample grades.
Piping utilizes 316L stainless steel and PTFE materials, suitable for testing various organic solvents and oils.
Features volume flush and time-based flush modes for convenient equipment operation and maintenance.
Suitable for laboratory or field testing; optional pressure reduction device enables online high-pressure measurement for real-time monitoring of particle contamination in oil systems.
Built-in particle contamination grade standards: ISO4406, NAS1638, SAE4059, GJB420A, GJB420B, ГOCT17216, GB/T14039, etc.
Customizable alarm levels for contamination or cleanliness detection.
Built-in moisture sensor and temperature sensor.
Built-in calibration function supporting GB/T21540, ISO4402, GB/T18854, and other standards.
Chinese/English input with one-click switching, featuring preset, input, edit, and save functions for convenient operation.
Extensive storage capacity with options for internal instrument storage or external storage devices.
Embedded design with a high-strength housing for portability, suitable for various types of construction machinery.
