DM-602-H2 (DM-602-H2)

The Detcon Model DM-602IS-H2 Detector is designed to detect and monitor H2 in air in a range of 0 to 1% by volume.

The sensor assembly consists of an electrochemical fuel cell mounted in a stainless steel and ABS plastic housing incorporating a splash guard with integrated heat port, a signal conditioning control transmitter circuit, a base board and a 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.
