Description
Overview
GAOTek dust particle air quality tester is a test instrument applied to cleanliness monitoring and micro-particle counting detection in clean environment. The counter is theoretically based on the light scattering principle and achieves the detection of dust particle size and particle count through photoelectric sensing technology. It has the features of visualization for easy calibration, good stability, high measurement accuracy, small size, light weight, easy installation, etc. It is widely used in clean scenes of pharmaceutical, electronics, semiconductor, hospital operating room, aerospace, precision processing, environmental protection, microbiology, food industry, etc.
