Features: For on-site online testing, real-time monitoring of various hydraulic and lubrication system oil particle pollution. Adopting the principle of light resistance method (shading method), it has the advantages of fast detection, strong anti-interference, high precision and good repeatability. High-precision sensor to ensure high-resolution force and accuracy; Built-in GB / T14039, ISO4406, NAS1638, GJB420A, GJB420B particle pollution degree standards, and according to user requirements built-in required standards. Built-in calibration function, according to ISO4402, GB / T18854-2002 (ISO11171: 1999) and other standards for calibration. Two calibration curves (ACFTD calibration curve, ISOMTD calibration curve) can be stored at the same time, and can be easily switched to reduce the conversion error. RS232 interface or RS485 interface CAN interface, an external computer to complete the test data transmission, storage and processing. The instrument can achieve continuous automatic online detection, real-time particle number and level can be given, and can set the detection interval. Flow through the sensor for real-time monitoring. High-strength aluminum shell, strong anti-interference, high temperature and pressure, strong shell, can be used in harsh environments. Technical Parameters: Light source: semiconductor laser Particle size range: 1μm ~ 600μm (depending on the sensor used) Sensitivity: 1μm (ISO4402) or 4μm (c) (GB / T18854, ISO11171) Counting volume: 10ml Counting accuracy: ± 0.5 levels of pollution Test sample temperature: 0 ℃ ~ 80 ℃ Operating temperature: -20 ℃ ~ 60 ℃ Storage temperature: -30 ℃ ~ 80 ℃ Power supply: 100V ~ 265VAC or 9 ~ 11VDC
