Particulate Monitors

Aerosol photometers operate by detecting scattered light. The amount of light reaching the detector is proportional to the number of particles passing through the detection chamber. Also known as nephelometers, these instruments are used to monitor particulate matter such as dusts, smokes, mists, and fumes. They can be used for monitoring the respirable fraction of dust, and are small enough to use for personal exposure monitoring. Results are reported in μg/m³ or mg/m³.

Thermo Scientific pDR-1000AN

The personalDataRAM™ pDR-1000AN passively measures mass concentrations of dust, smoke, mists, and fumes in real time, and sounds an audible alarm whenever the user-defined level is exceeded.

Highest performance of any real-time personal particulate monitor – Measurement range from 0.001 to 400 mg/m³ (auto-ranging).
Rugged and extremely compact – Palm sized pDR-1000AN weighs only 18 oz. (0.5 kilogram) and can be attached to a belt or shoulder strap, hand held, operated on a table top, or mounted on a tripod.
Simple zeroing and calibration – The pDR-1000AN comes gravimetrically calibrated (NIST traceable) in mg/m³ using standard SAE Fine (ISO Fine) test dust. Zeroing with particle-free air is accomplished quickly and effectively under field conditions using the zeroing kit included with the instrument.
Safety approvals and certifications – The pDR-1000AN complies with US FCC rules (Part 15) and has received CE certification. It also has intrinsic safety approval from the US Mine Safety and Health Administration (MSHA) for use in coal mining environments containing methane gas.
