AAPQMS-19C works on Laser scattering principle which allows immediate and continuous measurement of 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.The Microprocessor & PLC based technology helps the system to perform accurately & efficiently. 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.

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.
