PC-3A Multi functional Laser Dust Continuous Tester

1、 Product Overview

The PC-3A multifunctional laser dust continuous tester is used to measure the concentration of inhalable dust (PM10, PM2.5, and total dust TSP) in the air of public places and the number of dust particles with a particle size of (0.3-10.0) μ m per unit volume of clean environment air. It is a real-time and rapid measuring instrument for the disease prevention and control center, health supervision, environmental monitoring and other departments to measure the above items. This instrument adopts the principle of light scattering and uses semiconductor laser as the measurement light source to perform high-sensitivity non-contact measurement 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 real-time and fast display in Chinese. The instrument is also equipped with environmental temperature and relative temperature testing devices, and has functions for dust concentration testing and dust particle counting.

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. It is suitable for measurement in situations without power supply and can be widely used in various public places and fields such as electronics, optics, food, aerospace, and aviation.
