Which manufacturer produces a good dust detector?
At present, the domestic standard dust concentration detector is Shenzhen Sainavi manufacturers, mainly CW-76S automatic dust concentration detector, the instrument is Sainavi independent research and development set of aerodynamics, digital signal processing, photoelectricity, integration of high-tech products, mainly used to detect the atmospheric concentration of dust quality, applicable to construction sites, urban grid monitoring, mobile monitoring and other fields It is the core module of the atmospheric quality detection system.
How does the dust detector work? What is the principle?
Dust detector referred to as dust meter, also known as dust meter or dust tester, is mainly used to detect the dust concentration in the ambient air, the type of dust meter is divided into: laser dust meter, on-line continuous monitoring of dust meter, portable dust meter, etc., the dust meter is widely used in the Centers for Disease Control and Prevention, mines, metallurgy, power plants, chemical manufacturing, health supervision, environmental protection, environmental online monitoring etc. Dust detector, the working principle of the main light scattering method, beta ray, AC electrostatic induction principle; applicable to a variety of research institutions, meteorology, public **** health, labor health, air pollution research. Rapid detection instrument mainly has five methods: light scattering method, β-ray method and micro-weight balance method, electrostatic induction method, piezoelectric balance method.
Shenzhen Biru Blue Environmental Technology Co., Ltd. is by focusing on the field of intelligent environmental protection for many years the technical team created by the high-tech companies, the company's handheld dust detector using the principle of light scattering to the semiconductor laser as the measurement of the light source, the dust in the air for highly sensitive non-contact measurement. By the single-chip microprocessor management and control of the whole process of testing, using high-resolution large-screen high-brightness liquid crystal display, full Chinese display. Used for industrial and mining enterprises dust concentration detection and exceeding the standard alarm, with dust concentration test alarm and dust particle counting function, is the Center for Disease Control and Prevention, Labor Health Supervision, Environmental Monitoring, Industrial and Mining Enterprises and other departments of real-time rapid measurement of a new generation of intelligent measuring instruments.
