Electrochemical Toxic Gas Sensor Technology
"Detecting The Difference"
Electrochemical Technology • Quick Response Time • Long Term Calibration Stability • Low Power Consumption Detcon toxic gas electrochemical gas sensor assemblies are designed to monitor ambient air for the presence of a wide variety of toxic gas compounds. The Detcon list of measurable toxic gases and the availability of full-scale ranges are among the most extensive in the gas detection industry. The detection technology is the 3-electrode electrochemical cell type. Each cell consists of three electrodes embedded in an electrolyte and is housed beneath a gas diffusion membrane. Sensitivity and specificity to each target gas is achieved by varying the composition of the electrodes and/or the electrolyte solution. The electrochemical cell is the most widely applied sensor design for detection of toxic gases. While there are certain specific applications where other sensor designs can be used to good effect (e.g. the metal oxide semiconductor and the photo-ionization detector), the electrochemical cell remains the most widely accepted for use in monitoring a broad range of gases. Detcon has a long history in the adaptation and application of electrochemical sensors, and the resultant product line makes optimal use of the many advantages of the technology. In addition, an Intrinsically Safe UniTox™ DM-200 version is covered separately.

The controlling circuit maintains an external operating voltage between the sensing and counter electrodes sufficient to drive the electrochemical reaction. The electrochemical reaction with the target gas generates a current flow between the sensing and counter electrodes. This current is proportional to the target gas concentration and is reversible. The electronic circuit also provides a specific bias potential between the reference and the sensor electrodes in such a manner that no current flows between them. The quick response of the sensor results in continuous monitoring of ambient air conditions.
