1. Product Overview
KQET-5018S low flow 2.83L 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. This instrument has the characteristics of easy visualization for calibration, good stability, high measurement accuracy, small size, light weight, and easy installation. It is widely used in clean scenarios such as pharmaceuticals, electronics, semiconductors, hospital operating rooms, aerospace, precision processing, environmental protection, microbiology, and food industries.
