Automatic Oil Cleanliness Tester NAS1638
Product Model: JF14039Z
Product introduction:
According to ISO11171-1999, ISO4406, NAS1638, GJB420A, GJB420B, SAE749D, ГОСТ17216, AS4059D and other relevant international standards, it is developed by the principle of photoresist method (shading method), Used to detect the size and quantity of solid particles in liquids. It can be widely used in aerospace, electric power, petroleum, chemical, transportation, ports, metallurgy, machinery, automobile manufacturing and other fields. ), turbine oil (turbine oil), gear oil, engine oil, aviation kerosene, water-based hydraulic oil and other oils are tested for solid particle contamination, and organic liquids and polymer solutions are tested for insoluble particles.
Performance characteristics:
1. Adopting the principle of photoresistance method (shading method), it has the advantages of fast detection speed, strong anti-interference, high and good repeatability;
2. High-density sensor ensures high resolution and accuracy;
3. The dense syringe sampling system realizes constant sampling speed and sampling volume control.
4. Positive/negative pressure air chamber device to realize sample degassing and high-viscosity sample detection.
5. 6 inch true color LCD touch screen, touch operation, simple and convenient.
6. Built-in GB/T14039, ISO4406, NAS1638, GJB420A, GJB420B, SAE749D, ГОСТ17216, AS4059D and other particle pollution grade standards, and built-in required standards according to user requirements.
7. As many as 9900 particle size channels, convenient for particle size analysis.
8. Four calibration curves (latex ball calibration curve, ACFTD calibration curve, ISOMTD calibration curve, ГОСТ17216 calibration curve) can be stored at the same time, and can be easily switched to reduce conversion errors.
9. Test data storage function, convenient for archiving, retrieval and analysis of test data.
10. The built-in printer can print out the test report directly.
11. Built-in English input method to realize English labeling of test report.
12. RS232 interface and powerful data software can realize the control of the instrument by the external computer and the processing of the detection data.
13. With magnetic stirring, the particles are evenly distributed.
