Instructions for Online Atmospheric Dust Detector

Jiangsu Weina Taike Instrument Manufacturing Co., Ltd. has successfully developed an online atmospheric dust detector. As is well known, with the reform and opening up and industrialization process, China's atmospheric haze, dust particles, and dust have reached a very serious situation and are also the main culprits causing air quality pollution. With the requirement for online detection of atmospheric dust, our company has implemented industry standards such as "Light Scattering Measurement Method for Dust Concentration in the Air" and "Inhalable Particulate Matter in Public Places Air" according to the Ministry of Health standard(PM10)Determination method-Light Scattering Method. Designed an online detection device that provides a high-performance detection method for online detection and installation.Specially applicable：The dust generated by construction sites and roads is greater than75umParticle concentration detection.

Domestic online atmospheric detection mainly uses beta rays, with long measurement time and high prices10Over ten thousand, our company has successfully developed a product that uses laser principles.2Produce a test result every minute and measure:PM10ThePM2.5Greater than75umInstruments for measuring particle number and mass concentration.

At present, domestically produced handheld dust detectors have small flow rates and large errors, which cannot guarantee measurement accuracy. Our company has successfully solved this series of problems and provided a high flow, online, remote communication instrument for atmospheric dust detection, which can simultaneously measure particle number and concentration.

Principle and structure of online atmospheric dust detector

The external air of the detector enters the suction port, passes through the maze cutter to remove coarse particles, blocks external light, and enters the detector darkroom. The parallel light in the darkroom intersects with the field of view of the light receiving part at a right angle to form a sensitive area (indicated by the diagonal line in the figure). When dust passes through the sensitive area, it90The scattered light in the direction of ℃ passes through the slit and enters the photomultiplier tube to be converted into photocurrent, which is then converted into the number of pulses per unit time proportional to the scattered light by the photocurrent integration circuit. Therefore, recording the number of pulses per unit time can determine the relative mass concentration of dust.

By using microcontroller resolution technology and imported light sources and detectors, the stability and accuracy of the instrument have been improved to an internationally advanced level.
