Thermoelectric Cooled Gaseous Sampler

Sample up to four gases simultaneously at temperatures up to 20 degrees below the ambient temperature.

Available Model : PEM–TECGS-1

We offer thermo-electric cooled gaseous sampler which can be used as stand-alone sampler independent of a particulate sampler. Using suitable chemical reagents, upto four gases such as SO2, NO2, O3, Cl2, H2S, NH3 etc can be sampled for subsequent analysis in a chemical laboratory.

PEM–TECGS-1 utilizes thermo-electric cooling for keeping the impingers at the desired temperatures during sampling.

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

Thermoelectric Cooled Gaseous Sampler TECGS 1

Physical Design Highlights :

The sampler comprises a built-in pump, timer, time totalizer, thermo-electric cooled cold box for four glass impingers, a power supply for Peltier thermo-electric module, a rotameter and four way valve manifold. The provision of Peltier cooling reduces the temperature of adsorbing solution which enhances the efficiency of adsorption while also helping in reduce evaporation losses particularly for sampling in hot and dry ambient conditions.

Salient Features :

  • Sampling of Four gases simultaneously.
  • Thermo-electric cooling of chemical adsorbents.
  • Cooling of more than 200C from ambient environment.
  • Compact and light weight
  • Built-in Sampling pump, timer and time totalizer
