Personal Air Sampler PAS 1
Carry it on your person to sample the air you are breathing.
Personal Air Sample is a battery operated mini air sampler that can be clipped on to a person to enable hands-free sampling of inhalable gaseous pollutants and particulate matter in the air actually breathed by the person at work place.
Available Models : PEM–PAS-1A, PEM–PAS-1B, PEM–PAS-1C, PEM-PAS-1L
Polltech provides three models of Personal Air Samplers. They basically differ in their application. Model PEM-PAS 1 and PEM-PAS 1A are designed for sampling of particulates using filter paper while Model PEM-PAS1L is suitable for sampling of toxic gases in work place by entrapping them on specific adsorption tubes. The suction capacity of the pumps used is different for various models resulting in different sizes of the samplers.
Applications :
- For monitoring air quality on shop floor
- Workplace monitoring
- Fugitive gas monitoring
- Used in workplace of industries like Chemical, Paint, Cement, Fertilizers, Sugar etc
- Exposure studies of Personnel in hazardous areas
- Elderly care facilities
- Laboratories
Physical Design Highlights :
Each Personal Air Sampler comprises a sampling medium holder, a suction pump, a flow measuring device, a flow controller and a battery.
An appropriate filter placed in the filter holder forms the sampling medium for sampling of dust or particulates. The medium for sampling of vapours and gases, is an adsorption tube which is packed with pollutant specific like Activated Charcoal, Tenax GC adsorbent etc.
Only one of the two media, either filter or the adsorption tube can be used at a time.
A low power diaphragm type suction pump provides the suction for drawing of air through the sampling medium. It is powered by a high capacity rechargeable Li-ion battery. Flow is measured by a specially designed compact rotameter. Flow control is effected through a ball valve or a needle valve or an electronic circuit.
Salient Features :
- Battery Operated Model with rechargeable battery.
- Used in Shop Floor or Workplace Air Quality Monitoring.
- Compact and Light Weight weighs less than 500 grams
- The filter holder or adsorbing tube can be held at the breathing level for measurement of TLV exposure.
- Can be carried on the person
- Easy to carry, easy to use, affordable model.
