APEX 2 Air Sampling Pump

They control the flow of air very carefully to ensure a known volume of air is sampled. So when monitoring for dusts, where the back pressure will increase as dust is collected, the pump maintains the flow at the correct level.

Monitoring for dust is usually achieved by sampling air onto a pre-weighed filter, which is then weighed after sampling and the dust concentration calculated. Monitoring for gases and vapours uses the same air sampling pump, but generally at a lower flow and using sorbent tubes or other media.The Apex2 range of personal sampling pumps are the next generation, offering class beating performance with great new features.
