Handy Air Sampler HAS 1
Sampling for toxic gases and VOCs at low flow rates
Low Flow Air Sampler is an easy-to-carry around sampler for determining the concentration of toxins in ambient and workplace environments.
Available Model : PEM – HAS1B
PEM–HAS1B is a compact, light weight battery operated sampler which is is designed for determination of toxic pollutants such as SO2, NO2, Cl2, NH3, H2S etc. in ambient and workplace environments. The sampler employs wet chemical methodology for sampling the air for toxic gas and other pollutants.
Applications :
- Compliance Monitoring in industrial areas
- Investigative Air Monitoring for pollution surges
- Workplace monitoring for exposure compliance
- For monitoring emission from fume hoods, ducts etc
- Fugitive gas monitoring
- Sick Building Investigations
- Factory Act Compliance
- Data Collection and Reporting
Physical Design Highlights :
PEM–HAS1B comprises a sampling train, a suction pump, a flow measuring device, a flow controller and an Electronic assembly. The sampling train accommodates two glass impingers which are housed in thermocole housing. The two impingers are connected pneumatically in series; the sampled air is made to flow through them in succession and a single flow measuring device and a single flow control device is used. It, therefore, permits sampling for only one pollutant at a time Pollutant-specific adsorbent solutions are placed into the glass impingers for entrapping the pollutants of interest. Each sampler is made of corrosion free Stainless Steel and houses all the components and subassemblies.
The sampling suction pump is of diaphragm type. The air flow is measured by a single precision low range rotameter. Flow control is carried out by a mini ball valve placed in series with the sampling pump.
Salient Features :
- Useful for sampling one gas at a time using two impinger tubes.
- Battery Operated with in-built battery charger and external adaptor as DC source.
- Used in Shop Floor or Ambient Air Quality Monitoring.
- Microprocessor Based Electronic Timer Cum Time Totalizer
- Compact and Light Weight
