Electrochemical

Electrochemical sensors work on a different principle from the pellistor and IR devices. With electrochemical sensors the target gas undergoes a chemical reaction, producing a current that is directly proportional to the concentration of gas present. The sensors use very little power and show good responses to various gas concentrations over a wide range of ambient conditions.

A range of 20 mm electrochemical sensors is available for several toxic gases including Carbon Monoxide ,Hydrogen Sulfide and Oxides of Nitrogen and Sulfur. These sensors are ‘drop-in’ replacements for existing sensor types in this size.

The range of toxic sensors is complemented by the EC410 , RoHS compliant, Oxygen sensor. This unique sensor contains no lead, has a greatly increased life span and is of significantly lower mass compared to other Oxygen sensors of this size. The sensor contains no consumable components.
