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.
SGX Sensortech are pleased to announce the launch of eight new sensors to complement their range of industrial and commercial gas sensing products. The new products allow instrument manufacturers a greater choice when selecting sensors for carbon monoxide, hydrogen sulfide and oxygen and are available in two industry standard packages; 20mm and 32mm diameter.
In addition, SGX are proud to include an innovative combined carbon monoxide and hydrogen sulfide sensor in the same package which provides industry compliant performance in a single miniature housing, saving valuable space in portable instrument designs.
