This product is used for long-term monitoring of the concentration of suspended particles in the air. It can monitor the concentration of atmospheric particles such as PM2.5 and PM10 with the corresponding cutter. The instrument adopts the principle of β-ray absorption, which is an automatic measurement method equivalent to the weighing method and fully complies with the relevant laws, regulations and standards of China. Due to the use of automatic measurement methods, errors caused by human operation can be effectively avoided. At the same time, the equipment uses a stable low-energy β radiation source, which does not require frequent calibration and zeroing, effectively improving work efficiency.
It meets the new particle detection standards in 2021. The detector uses a proportional counter, with a large effective detection area, good consistency, high stability, negligible detection signal attenuation, and low failure rate.
The test concentration is refreshed in real time and continuously, truly realizing real-time second-level monitoring.
The paper feed uses time and concentration dynamic judgment, with a long interval time, which greatly reduces the amount of paper tape used and reduces operation and maintenance costs.
It can be applied to mobile laboratories, indoor air quality monitoring, urban air quality monitoring and overall air quality monitoring in industrial parks.
