New Personal Air Sampler PAS 2
Our range of personal Air Samplers PEM–PAS-1A, PEM–PAS-1B, PEM–PAS-1C, PEM-PAS-1L are reputed products. They owe their popularity to their compact and lightweight construction which makes them suitable for clipping to the body of a person. The design allows unhindered movement at work place while simultaneously carrying out sampling of inhalable gaseous pollutants and particulate matter in the air actually breathed by the person wearing the sampler.

In tune with our philosophy of utilizing state of art techniques, we now offer a ‘Next Generation’ Personal Air Sampler Model PEM-PAS 2 with enhanced features
