DM-534 Oxygen Sensor

Brand: Detcon Inc

Detcon Model DM-534 sensor is designed to detect and monitor O₂ in air over the range 0-25% by volume. 

The sensor assembly consists of an electrochemical fuel cell mounted in a stainless steel housing that includes a splashguard with integral cal port, a signal conditioning control transmitter circuit, a base connector board and an explosion proof junction box. 

Operator interface is via a small handheld magnet. 

One of the main features is the embedded intuitive software that guides the user through routine calibration and configuration menus using a built-in LED alpha/numeric display.
