This modelAir purifier detectorIt is an instrument dedicated to measuring the number of dust particles per unit volume at the inlet and outlet of an air purifier, and calculating efficiency based on the number of dust particles at the inlet and outlet. It is independently developed by our company based on the absorption of advanced high-sensitivity microsensor technology from abroad, integrating aerodynamics,digital signal processing,High tech products integrating optics, mechanics, and electronics. The basic principle is that the detection laser of the optical sensor is scattered by dust particles and received by the photosensitive element to generate a pulse signal. The pulse signal is output and amplified, and then subjected to digital signal processing. By comparing it with the standard particle signal, the comparison results are represented by different parameters, and the parameters of the space before and after purification are calculated and displayed for purification efficiency. The measurement parameter settings and calculations, measurement result display, buttons, time, date, etc. of this instrument are all controlled by a built-in microcomputer(MCU)Control and implementation.

ThisAir purifier detectorAccording to the air sampling flow rate1rise/It can simultaneously detect two particle size ranges. It has the characteristics of high measurement accuracy, stable performance, strong functionality, small size, and simple and convenient operation, reaching or exceeding the performance indicators of similar international products. It can be widely used for indoor and outdoor environment detection,Effectively reflect the number of dust particles in the current environment; At the same time, the purification efficiency of the air purifier can be reflected in real-time. therefore,It is also very suitable for testing the purification effect of air purifiers.
