1. Product Overview
The KQET-5104 high flow 28.3L online laser dust particle counter is a testing instrument used in the fields of cleanliness monitoring and particle counting detection in clean environments. The counter is based on the principle of light scattering and uses photoelectric sensing technology to detect the particle size and count the number of dust particles. Compared to small flow counters, this instrument has a sampling flow rate of 1CFM (28.3L/min), a larger sampling flow rate, and more accurate detection. It has become an essential instrument for pharmaceutical GMP certification. Similarly, this instrument can also be applied to other clean environments such as electronic factories, hospital operating rooms, aerospace, precision processing, and the food industry. This instrument has the characteristics of high measurement accuracy, small size, light weight, and easy installation.
2. Product features
