Fixed Type Gas & Flame Detection

DT Tox

Electrochemical type
4 to 20 mA gas transmitter for detection of toxic gases and vapours. The DTEx is an explosion proof gas detector for continuous monitoring of toxic gases and vapors in ambient air, the transmitter uses industry standard three wire analog technology and converts the signal from a electrochemical sensor to 4-20mA signal that is proportional to the actual gas concentration. The unit is designed for  one man calibration and easy to operate. The toxic gas sensing head can be used in safety and engineering applications for oil and gas platforms, chemicals and petrochemical plants and other facilities where toxic gases are used.
