Product Description:

OC-9500 Dust monitoring system with beta ray adopts the working principle of beta ray attenuation to automatically measure and record airborne particulate concentration. The C14 emits a constant source of high-energy electrons (known as beta rays) through a spot of clean filter tape. These beta rays are detected and counted by a sensitive scintillation detector determine a zero reading. The OC-9500 system automatically advances this spot of tape to the sample nozzle, where the vacuum pump will pull the measured and controlled amount of dust-loaded air through the filter tape. Then the dirty spot will be placed back between the beta source and the detector, so causing an attenuation of the beta ray signal, which is used to assure the mass of the particulate matter on the filter tape.

According to the sampling flow, sampling time, filter membrane area and environmental parameters, the working condition concentration and standard condition concentration of particulate matter in ambient air are calculated to realize the automatic monitoring of ambient air particulate matter.

Applications:

Mining site, Quarries area, Smart city project, Urban ambient quality inspection, Port environmental monitoring, Dust detection in Ceramic factory, Tourist attractions, Surface Mining Garbage landfills, etc.

Function:

Highly accurate of PM2.5 and PM10 real-time monitoring, also supporting the Meteorological parameters (Temperature, Humidity, Wind speed, Wind direction, Air pressure) and Noise.

The DHS can eliminate the influence of the humidity on the measurement results and ensure the accurate measurement of semi volatile nitrate and organic compounds.

Adopt the advanced temperature and humidity compensation algorithm to ensure the accuracy of the monitoring data.

Automatically record the sampling data, once power off the data will be saved automatically and will start sampling after power on.

Support the data transmission of 4G LTE, RS485, etc.

Modular design and low maintenance costs.
