High Volume Samplers are the basic instruments used for monitoring dust in Ambient Air.They are in widespread use all over the world. In these samplers, air borne suspended particulate (SPM) are measured by passing air at high flow rate through a high efficiency filter paper which retains the particles and provisions have been made for simultaneous sampling of gaseous pollutants also.

Envirotech APM 430 has a continuous duty blower with brushless motorto ensure continous woking upto 28 hours. Noise level has also been reduced by using noiseless blower.It also has provision for gaseous sampling for eg. NOx  It is more compact and lighter can be carried in a car trunk and is ideal for field use.
