If you need a portable, easy to use oxygen (O2) monitor - we’ve got you covered. 

Product Overview

The Analox 101D2 oxygen (O2) analyzer is a battery powered, portable instrument which provides a continuous digital display of the oxygen (O2) concentration, in the gas sample, presented to the front surface of the sensor unit.

The instrument has two ranges:

  • 0.01% - 19.99%
  • 0.1% - 100.0%

The sensor assembly incorporates advanced circuit design which provides automatic temperature compensation over the range -10°C to 40°C.

The instrument is easy to calibrate, requiring only a single adjustment and is user settable. High and low, audible and visual alarms are fitted as standard.

Ensuring the oxygen (O2) content is sufficient to keep divers working is of paramount safety and is also an IMCA requirement. Audio/visual alarms are also required and are a standard feature of the 101D2.
The most commonly used oxygen (O2) monitor globally on air diving spreads, the 101D2 is ideal for monitoring the DDC environment and the diver's gas feed.
Optional extra facilities can be specified at time of ordering. These include:

  • An analogue output voltage
  • Relays which operate in alarm conditions
  • A 4 – 20mA Sensor Input to accommodate a remote loop powered Sensor
  • Transmitter.

Optional extras require the fitting of the 0 – 30vDC external power facility.
