APM 460 DXNL is one of the most advanced PM10 samplers being manufactured in India. It is based on CSIR NEERI technology and is the only PM 10 sampler in India that conforms to BIS 5182 (Part 23): 2006
Automatic flow controller and auto shut off
In all previous models of particulate samplers in use in the country, the sampling rate varies with dust loading on the filter and fluctuates with changes in the mains voltage. The APM 460 DXNL uses an electronic flow controller to automatically maintain constant sampling rate through the filtercyclone assembly. The size fractionating cyclone of the APM 460 DXNL thus operates close to its designed separation velocity resulting in a sharper cut-off for particulates larger than 10 microns. When the dust load on filter becomes excessive and exceeds the capacity of the blower the electronic circuits provided in the flow controller automatically shut down the machine.
