This instrument is mainly used to test the purification efficiency of the air purifier, suitable for sales staff, as well as the importance of purification of air purifier, need to be detected at any time the personal use of air pm2.5.If used in factories, laboratories and other places, you need to choose other models.CW-HPC200 (A)Air purifier detector efficiency is dedicated to measuring the air purifier air inlet and outlet in unit volume, the number of dust particles and according to the number of inlet and outlet of dust particles to calculate the efficiency of the instrument.It is a set of air dynamics of Shenzhen City Environmental Technology Co. Ltd. trade power absorption of high sensitivity micro sensor foreign advanced technology on the independent development of the,digital signal processing,Light mechanical and electrical integration of high-tech products. The basic principle is that the laser is scattered by dust particles,Digital signal processing of pulse signal output from optical sensor,Measurement parameter setting,The results show that buttons, time, date, etc. by the built-in microcomputer(MCU)Control and implementation.
