DM-534 O2

The Detcon Model DM-534 Detector is designed to detect and monitor O2 in air over a range of 0 to 25% by volume.

The sensor assembly is comprised of an electrochemical fuel cell mounted in a stainless steel housing that includes a splashguard with an integrated heat port, a signal conditioning control transmitter circuit, a base connection board, and an explosion-proof junction box.

The operator interface is via a small pocket magnet. One of the key features is the intuitive, built-in software that guides the user through routine calibration and setup menus using an integrated alphanumeric LED display.
