CAAQMS-91 is an advanced Continuous Ambient Air Quality Monitoring System designed to measure key environmental parameters such as Particulate Matter (PM10, PM2.5), gases (SO₂, NO₂, CO), temperature, humidity, and atmospheric pressure. It follows US EPA-approved measurement technology, ensuring reliability and accuracy for both industrial and urban applications.

The system can be seamlessly integrated with meteorological sensors to offer a comprehensive environmental monitoring solution. PRIMA’s CAAQMS-91 is primarily used to assess the concentration of pollutants in specific areas, helping industries and municipalities evaluate air quality and ensure workplace and environmental safety.

Ideal for air pollution monitoring networks, construction zones, and high-dust activity areas, the system also supports mapping inhalable particulate exposure over time. This aids in pollution control strategies and forecasting pollutant concentrations using spatial and temporal data analysis.

THE PERSONAL AIR SAMPLER Model PAS25 consists of a mini pump driven by a D.C. motor working on a 6 volt rechargeable battery. These work continuously for up to 10 hours between charging. If required, the air sampler can be used, while charging by 220 V AC mains supply. The screw arrangement allows variation of flow rates between 0.5 and 2.5 litres/minute. A flow meter is mounted on the face of the box.

Pulsation dampers are internally fitted on the inlet and outlet gas circuit to smoothen the air flow. The pump unit is fitted into a M.S. case of compact size. The sampler unit can be kept on a flat surface for stability at the breathing zone level of the worker to take STEL(15 mins.)/ TWA-TLV (8 hour) measurements. The air sampler is supplied with battery charger in a carrying case.
