The Millennium II Oxygen (O2) Deficiency Detector is designed specifically to alarm when oxygen levels deviate from the ambient value of 20.9%. It provides a fast, accurate and repeatable response within a detection range of 0 to 25% oxygen. The O2 sensor is completely compatible with the Millennium II Single Channel, Dual Channel, and BASIC transmitters.

The Millennium II maintains an uninterrupted digital signal between the sensor and the transmitter, from up to 2000ft away! It can communicate seamlessly with external safety equipment, whether through Analog, Relay, Modbus RS485 or HART output configurations. The housing design offers easy access to the controller where the intuitive menu options, time and date stamp event logging, non-intrusive calibration and power switch can all be accessed through the innovative OLED graphic display. This OLED display is completely unique in the market, providing read-outs that are visible in darkness or bright sun, blistering heat or at temperatures as low as -55°C. All this amounts to a detector which stands alone in it's simple installation, calibration, and day-to-day operation.

The Millennium II is available in a stainless steel or aluminium certified housing, drawing minimal power and working across a wide power range, from 10.5 Vdc up to 32 Vdc.
