Ambient Dust Monitoring

Online PM10, PM2.5 dust monitor

Monitoring and Sampling

The SM200 provides both automatic monitoring of particulate matter as well as sampling of air on filters. Standard 47 mm filters are used.

Real-Time Particle Measurements

The SM200 can generate real-time data using particle counting. A laser diode based particle counting system is placed before the sampling filter. The number as well as the size of the particles are measured. The real-time data is calibrated using the results from the beta attenuation measurements.

Beta Attenuation

The SM200 is an automatic particulate monitor for monitoring of PM10 and PM2.5. A filter is loaded into the filter magazine and a Geiger counter detects the beta attenuation before and after sampling. The measurement time of the instrument is 8–24 hours
