Harsh Area Gas Sampling System


A custom designed single or multiple sensor sampling system suited for monitor of gas or vapor atmospheres from extreme environments containing temperature, humidity, particulate or pressure challenges.

  • Designed for continuous monitoring in hazardous and non-hazardous area locations
  • Reduced sensor replacement & maintenance costs due to moisture & contamination control
  • Proven design used for sampling from sewers, digesters, drains, confined spaces, tank cleaning, exhaust ducts, etc
  • Faster response time with sample flow-through design powered by internal diaphragm pump
  • Humidity removal ensures accurate sensor readings even in highly humid environments
