Contamination Monitoring Continuous Particle Counter 28.3LPM DC24V

• Product Overview

KQET-5104 high flow rate 28.3L online laser dust particle counter is a test instrument applied to cleanliness monitoring and micro-particle counting detection in clean environment. The counter is based on the theory of light scattering principle and achieves the detection of dust particle size and particle count through photoelectric sensing technology. Compared with the small flow counter, the sampling flow rate of 1CFM (28.3L/min), the sampling flow rate is larger and more accurate, which has become a necessary instrument for GMP certification of pharmaceutical companies. Similarly, the instrument can also be used in other clean scenarios such as electronics factories, hospital operating rooms, aerospace, precision processing, and food industries. This instrument has the characteristics of high measurement accuracy, small size, light weight, easy installation, etc.
