1Introduction

The TW-2058AKL desktop oil particle counter is an instrument developed specifically for detecting pollution levels in oil based on standards such as GB/T 18854, ISO 11171, DL/T 432, GJB 420B, GJB 380.4A, NAS 1638, ISO 4406, etc. This instrument is developed based on the principle of light blocking, and is suitable for detecting particle contamination in hydraulic oil, lubricating oil, fire-resistant oil, insulating oil, and turbine oil. We can provide fast, accurate, reliable, and reproducible detection results, as well as complete pollution monitoring and analysis reports. Widely used in aviation, aerospace, power, petroleum, chemical, transportation, ports, metallurgy, machinery, automobile manufacturing and other fields.

2Main characteristics
