Product Overview
OC-9500 Beta-Ray Online Dust Monitoring System adopts beta-ray absorption principle, applies Carbon-14 as stable radiation source. Ambient air is sampled at constant flow, particulate matters are intercepted on filter tape. The beta ray energy attenuation value is detected to calculate dust mass concentration accurately. Combined with sampling flow, sampling time, filter area and environmental factors, the equipment outputs dust concentration under working & standard status automatically for 24/7 continuous online monitoring.
This integrated monitor is equipped with meteorological sensors (wind speed, wind direction, temperature, humidity, air pressure, noise optional), widely used in construction sites, factories, stockyards, ports and mines for fugitive dust emission supervision.
Core Features
- Beta-ray method measures dust mass directly, stable 24/7 data without seasonal correction
- Supports TSP, PM10, PM2.5 detection with matched particle cutters
- Integrated sampling & detection design effectively reduces measuring errors
- Built-in DHS heating + temperature & humidity compensation for high-precision testing
- Stable dual-channel sampling pump with long service life
- Mass data storage, supports USB export & power-off data protection
- Remote management: calibration, diagnosis, parameter setting and program upgrading
- 4G/Ethernet communication, follows HJ-212 protocol with over 99% data transmission rate
- Optional linkage with dust suppression devices for automatic over-limit control
- IP53 industrial enclosure, stably works in harsh outdoor environments
