Gas detection
Prima’s Continuous Ambient Air Quality Monitoring System (CAAQMS) is designed to continuously monitor a range of critical environmental parameters, including particulates (PM10, PM2.5), SO2, NO2, and CO, temperature, humidity, and atmospheric pressure, in accordance with US EPA criteria. The CAAQMS can also be used for meteorological measurements.
Prima’s CAAQMS-91 measures the concentration of gases and dust present in various urban and industrial locations to evaluate airborne pollution levels. It is also widely used in air pollution monitoring networks, in construction, or in freight handling areas. Organisations have also used this technology to measure daily inhalable particulate concentration levels by mapping an area’s atmospheric particulates, helping to accurately forecast pollutant concentration in the atmosphere.
The CAAQMS System was designed to be installed and exposed to the elements at the chosen monitoring location, for continuous monitoring applications.
The microprocessor and PLC-based technology help the system perform with precision and efficiency, providing operators with instantaneous readings of the level of pollutants displayed at the location where the system is installed. It can also interface with a computer for real-time and remote data acquisition and monitoring.
The CAAQMS’ on-screen, continuous display of concentration with actual date and time in tabulation, over-range identification, and graphical representation of each measurement make this system easy to operate for untrained personnel.
