• Augmenting Air Quality Monitoring Networks

The APM 460 is used for routine monitoring of PM10 in the ambient air. By using the APM 460, measurement of Respirable Particulate Matter can be done accurately and TSPM can also be assessed by collection of dust retained in the cyclone cup. The APM 460 gained acceptability from academic institutes consultants and a wide spectrum of industries besides country-wide use by the Pollution Control Boards and the National Ambient Air Monitoring Program.
Working Principals

The APM 460 sampler uses an improved cyclone with sharper cutoff (D50 at 10 microns) to separate the coarser particulates from the air stream before filtering it on the glass microfibre filter. APM 460 comes with a brushless, continuous rated induction motor to significantly reduce equipment downtime, maintenance efforts and inconvenience to the community. The brushless blower of the APM 460 also substantially reduces the audible noise. A thermal cut-out has been incorporated to protect the Blower motor from burnout due to overheating. With the improved motor design, the instrument no longer needs a voltage stabilizer resulting in cost saving and lowering the weight of the field instrument. The cabinet design has been improved to prevent entry of rainwater and dust into the machine
