手持式塵埃粒子計數(shù)器Brief Introduction
Airborne Particle Counter is an instrument used for the counting of particle amount and size distribution in clear environment. The main principle of the instrument is: after detecting laser of the laser sensor passed particles, the dispersed detecting laser is received by an optical sensitive component which will generate a pulse signal. The pulse signal is transmitted out and magnified. A conclusion can be made after the comparison between this signal and the pulse signal of standard particles. Through the MCU in the instrument, you can set parameters, print or store the results and time. The instrument can also report the humidity and temperature of the environment, as well as the working status of the laser sensor in the instrument. The design of the instrument follows the international standard (average Flow Rate of air sample is 2.83lpm). It can detect six kinds of particle size at the same time. Sample time can be set according to your request. The maximal sample time is 59min59sec. Sample data can be stored in built-in flash memory and transmitted out through a USB interface. The design of our Airborne Particle Counter is an innovation on American technology. The instrument has the features of high-accuracy, steady performance, strong function, small size, and being easy-to-use. Such features reached or surpassed that of other similar products in the international market
