Do particle counters require regular metrological verification and calibration？

A particle counter is an instrument used to measure the number and size of particles in a liquid. It has a wide range of applications, including aviation, aerospace, shipbuilding, weapons, nuclear industry, power, metallurgy, chemical, energy and other industries. However, regardless of the field, the oil particle counter needs to be calibrated to ensure the accuracy and reliability of the measurement results.

Firstly, in principle, the oil particle counter irradiates a liquid sample with a light source, and then scatters the particles in the liquid onto the detector through an optical system, thereby achieving measurement of the number and size of particles. However, this measurement method is influenced by various factors, such as temperature, humidity, pressure, and so on. The changes in these factors may lead to deviations in the measurement results. Therefore, only through regular calibration can these influencing factors be eliminated and the accuracy of measurement results be ensured.

Secondly, from the perspective of application scenarios, oil particle counters are usually used for monitoring and maintaining critical systems. For example, in the aviation industry, the oil particle counter is used to monitor the oil in the aircraft hydraulic system, detect particle pollutants in the hydraulic oil early, and ensure the safe operation of the aircraft. In the field of power, oil particle counters are used to monitor particulate pollutants in transformer oil and detect potential fault hazards early. Therefore, only through calibration can the measurement results of the oil particle counter be ensured to be accurate and reliable, providing accurate basis for the monitoring and maintenance of critical systems.

In summary, the calibration of the oil particle counter is very necessary. Calibration is a crucial step in ensuring the accuracy and reliability of measurement results, both in principle and in application scenarios.
