KQET-5128CL Large-Particle Built-in Pump Remote Laser Airborne Particle Counter with Flow Rate of 28.3L/min

The KQET-5128CL large-particle built-in pump remote laser airborne particle counter with flow rate of 28.3L/min is a testing instrument designed for counting comprehensive particle sizes in clean environments.

Innovatively breaking away from conventional approaches, this counter is built upon the principle of light scattering, utilizing photoelectric sensing technology to detect the size and count of airborne particles.

Compared to standard particle counters, this instrument offers an extended detection range—capable of measuring particles as small as 0.5μm and as large as 50μm. It is suitable for clean environments in industries such as electronics, lithium batteries, automotive, aerospace, precision machining, and food processing, where large particles may be present. This device not only addresses cleanliness assessment challenges handled by traditional particle counters but also resolves complex issues in process points where large particles are a concern.
