Model AAPQMS-19C works on EC sensor & Laser scattering principle which allows immediate and continuous measurement of Gas & fine particle present in the air both with respect to their number, their dimensions and their concentration in µg/m3. The system is designed for Continuous Monitoring Application to be installed open to sky at the prescribed monitoring location in the plant & urban areas. An instantaneous reading of the level of pollutants is displayed at the location of system installed. It offers a facility for interfacing to a computer for Real Time & Date Remote Data Acquisition & Monitoring. On screen, continuous display of concentration with real date & time in tabulation with over range identification and graphical representation of each measurement. High resolution readings at low cost, RTD based Continuous Monitoring, No Pre-heating time required, Non corrosive components are some of the key features of this system.
