TN-PC-3E
Laser inhalable dust continuous tester

overview
The TN-PC-3E laser dust analyzer is used to measure the concentration and cleanliness of inhalable dust (PM10, PM2.5) in the air of public places, with a particle size of (0.3-5.0) μ m per unit volume of air. It is a new generation of intelligent measuring instrument for real-time and rapid measurement of the above items by the Centers for Disease Control and Prevention, health supervision, environmental dust monitoring and other departments.
This instrument is a small portable measuring instrument that uses advanced light scattering principles and semiconductor lasers as the measurement light source to perform highly sensitive non-contact measurements of dust in the air. The entire testing process is managed and controlled by a single-chip microprocessor, using a high-resolution large screen high brightness LCD display with full Chinese language display. The instrument is also equipped with environmental temperature and relative temperature testing devices to facilitate users' inspection of the detection environment.
This instrument has the advantages of small size, easy portability, fast testing speed, high sensitivity, good stability, light weight, simple operation, and dual-use of AC and DC. Suitable for measurement in situations without external power supply. It can be widely applied in various public places and fields such as electronics, optics, food, aerospace, and aviation.
