Product Features

1. Adopt the light blocking (shading) counting principle established by the International Hydraulic Standards Committee
2. High-precision laser sensor with wide test range, stable performance, low noise and high resolution
3. The high-pressure injection pump sampling method is adopted, the sampling volume can be set by yourself, the injection speed is stable, and the sampling accuracy is high
4. The positive and negative pressure combined sampling system can achieve sample degassing, suitable for testing products with different viscosities
5. Built-in pressure sensor, you can directly set the pressure value and automatically determine the air pressure in the cabin to ensure safety
6. The host has a built-in air purification system to ensure that the test is not polluted. The high degree of integration avoids secondary contamination caused by the air tightness of the connection between the air pump and the test system.
7. Built-in multiple calibration curves, compatible with all commonly used domestic and foreign standards for calibration
8. Built-in GJB-420A, GJB-420B, NAS1638, GB/T14039, ISO4406, SAE4059cpc, SAE4059F, SAE749D, ГOCT17216, QC/T29104, JB/T9737, DLT432, HH005-2018 and more than ten other commonly used standards
9. Supports custom standard testing, can standardize the naming of custom standards, and make grade determinations
10. According to customer needs, up to 64 detection channels can be set simultaneously, supporting tens of thousands of particle size settings.
11. Built-in data analysis system, one test can provide all the built-in standard test data and contamination levels
12. It can perform cleaning detection, pre-set the target cleaning requirement particle concentration, display the cleaning status in real time during the cleaning process and automatically stop when the requirement is reached
13. The particle size can be set arbitrarily, and nearly 10,000 particle sizes are built in, which is convenient for particle size analysis
14. A variety of sampling containers such as standard sampling bottles or sampling cups can be used to meet the testing requirements of different industries
15. Full-function 7-inch color touch screen, Android system operation, Chinese and English dual interface, support up, down, left, and right sliding operation
16. Dynamic chart display of particle quantity changes during the test process
17. Built-in conventional calibration curve, other curves can be added as needed, manual, automatic, and half-count calibration are possible
18. Built-in multiple input methods, can be downloaded online, support handwriting input
19. The instrument has data integrity function, password login, multi-level authority management, operation log and data backup functions
20. Operator accounts can be set up unlimitedly, and operator permissions can be assigned individually
21. With guest login mode
22. With LAN interface, multiple USB interfaces, support Bluetooth and wireless communication functions (optional)
23. With massive data storage and printing functions, the machine can store data wirelessly and supports USB flash drive data storage, and data can be exported from the machine to a USB flash drive

OPC-L3 oil particle counter can be widely used in aviation, aerospace, electric power, petroleum, chemical industry, transportation, port, metallurgy, machinery, automobile manufacturing and other fields.
