Detcon Model DM-634 detectors are non-intrusive "intelligent" detectors designed to monitor ambient air for oxygen concentrations between 0 and 25% by volume.
The sensor assembly consists of a sensor in a stainless steel housing that includes a splash guard with a full cal port, a plug-in control transmitter circuit, a basic connection board and an explosion-proof enclosure.
