Data sheet


The Detcon Model DM-500IS-CLO2 Detector is designed to detect and monitor CLO2 in air in the 0 to 50 ppm range.

The sensor assembly consists of an electrochemical fuel cell mounted in a stainless steel and ABS plastic casing incorporating a splashguard with integrated heat port, a signal conditioning control transmitter circuit, a base card and a controller. explosion-proof junction box.

The intrinsically safe sensor housing design allows direct contact of the target gas with the electrochemical sensor, maximizing response time, detectability and repeatability.

And because the intrinsically safe case design does not use stainless steel flame arresters, it eliminates inaccurate readings due to target gas absorption.
