KQET-5018 remote laser airborne particle counter with low flow rate of 2.83L

The KQET-5018 series is a remote laser airborne particle counter with low flow rate of 2.83L, a testing instrument applied in the fields of cleanliness monitoring and micro-particle counting detection in clean environments.

Based on the light scattering principle, the counter realizes the detection of airborne particle size distribution and the counting of particle quantity through photoelectric sensing technology.

This instrument features visual calibration convenience, good stability, high measurement accuracy, small size, light weight, and easy installation. It is widely used in clean scenarios such as pharmaceutical, electronics, semiconductor, hospital operating rooms, aerospace, precision machining, environmental protection, microbiology, and food industries.
