Product Description


HOPU online oil particle counter, online oil pollution degree moisture detector is mainly capable of detecting the degree of particle contamination in oil and the moisture in oil.

It can online test and display degree of ISO/NAS,and PPM water content of hydraulic  lubricating oil, transformer oil,insulation oil etc, so that maintenance staff could take preventive measures in early period.

 The detection of particle contamination in the oil is built using a semiconductor laser. The principle of the photoresist method is used to measure the cumulative number of particles in the oil, which can conveniently detect the size of the metal particles in the oil and the flow rate of the oil. Compared with traditional classical measurement methods, it has wide adaptability.


1 Using laser sensor, the detection accuracy is high;

2 Fast detection speed: 6 seconds to give test results;

3 It can display ISO and NAS grade standards simultaneously by numbers and graphs;

4 The firmware is hard and not easy to damage, and the pollution level can be detected online under low pressure and high pressure;

5 Small in size and light in weight, it is convenient to carry, install, disassemble and install;

6 The oil flow through the instrument is small, which does not affect the normal operation of the entire hydraulic system;

7 Provide RS-232 serial cable and software CD to transfer data to PC or display;

8 Online printing and alarm functions are available, and these two functions are available as an option.
