Gas sensors

SARAD offers a wide range of gas sensors for various applications. These sensors can be mostly integrated into the enclosure of the instrument. Of course it is also possible to integrate OEM sensors chosen by the customer if the output signals are compatible with our instruments.
Due to the big number of target gases, different measurement principals with different behaviour regarding range, uncertainty, cross sensitivity and ambient conditions must be considered. Each user should clarify in advance the conditions and requirements for his application to select the best suited sensor.
Beside very complex and expensive analysis methods like gas chromatography or infrared gas spectroscopy, three major measurement principals are commonly used for monitoring and testing:
 
  • non-dispersive infrared spectroscopy
  • semiconductor detectors based on metal oxide
  • electrochemical sensors
 
With respect to the most frequent application fields we offer a number of standard sensors for our monitors. We use our own gas transmitters in case of semiconductor and electrochemical sensors. In case of NDIR sensors we implement parts from leading companies in this field.
 
Sensors for following target gases are available:

 

  • Oxygen (O2)
  • Carbon Dioxid (CO2)
  • Carbon Monoxid (CO)
  • Methane (CH4)
  • combustible gases (Methane, Propane, Buthane ...)
  • Hydrogen Sulfide (H2S)
  • Sulfur Dioxid (SO2)
  • Nitrogene Monoxid (NO)
  • Nitrogene Dioxid (NO2)
  • Chlorine (Cl2)
  • Hydrogen Cyanide (HCN)
  • Phosphene (PH3)
  • Hydrogen Chloride (HCl) / Hygrogen Bromide (HBr)
