KZ-4 Particle Counter

KZ-4 Particle Counter

Performance characteristics：

1. Suitable for on-site online testing, the instrument is equipped with mounting holes, which can

be mounted on the system to monitor the oil particle pollution (cleanliness) of various hydraulic and lubrication systems in real time.

2. The principle of photoresistance method (shading method), with the advantages of fast detection speed, strong anti-interference, high precision and good repeatabilit.

3. OLED screen display, film touch key operation.

4. Built-in standards for particle pollution levels such as NAS1638, ISO4406-1999, GJB420B-2006,

GJB420A-1996, and ROCT17216. And it can be customized with the required standards according

to user requirements.

5. Built-in"full-channel" standard, which can simultaneously detect the quantity of particles of 8

different fixed sizes.

6. Built-in calibration function can be calibrated according to ISO4402, GB/T18854-2002

(ISO11171:1999) and other standards.

7. Automatic online detection, which can display the number and grade of particles in real time, and can also be switched to a mode that only shows the grade.

8. An in-built water activity sensor can be installed to detect the water activity (aw value) and oil

temperature in the oil.

9. Real-time monitoring of the flow passing through the sensor.

10. High strength cast aluminum shell, strong anti-interference, high temperature and high pressure

resistance, strong shell, can be used in harsh environment.

11.Standard RS485 communication，Optional 232 communication, Modbus communication or 4-20mA communication can also be selected. Corresponding communication protocols are provided. It can be connected to a computer or an upper-level machine to complete the control of the instrument and the transmission, storage and processing of detection data12.The interface can be switched between Chinese and English, and four communication modes can also be switched13.
