  • Simple Calibration: O2NE+ can be calibrated on "pure air" which is easy to source and ship globally and affordable too
  • Long Life O2 Sensor: Can last up to 10 years*
  • Minimal Maintenance: Unlike other oxygen monitors, the O2NE+ only needs calibrating every 18 months and the sensor does not need changing every 2 years
  • "Plug and Play": O2NE+ is easily wall-mounted and basic installation does not require a qualified electrician
  • Repeater Included: O2NE+ comes complete with a repeater which is to be placed at the entrance to provide an early warning before entering the room
  • Suitable for Use with Helium: Presence of helium can affect the readings of most O2 monitors but the O2NE+ will provide accurate, reliable readings if helium is one of the gases you are concerned about
  • No Risk of Accidental Calibration: O2NE+ does not allow the user to calibrate it using ambient air. A certified calibration gas must be passed over the sensor at 18 month periods. This is a safety feature which prevents a potentially false calibration being made.

* Oxygen sensor lives are affected by variables such as the amount of oxygen they are exposed to and the environmental temperature and humidity.

This Analyzer uses Analox Sensor:


The Analox O2NE+ is an oxygen depletion monitor ideal for use where there is threat of a potential leak or build-up of an inert gas such as: Nitrogen, Argon and Helium. The O2NE+ provides two audio visual alarms which are preset at 19.5% & 18% (but can be adjusted) to warn personnel of a potentially dangerous depletion of oxygen in the workplace.

The use of inert and specialty gases is widespread and varied and includes many industries and processes, some of which are commercial diving, technical scuba diving, welding shielding gas, light weight aircraft fuel, packaging and breathing observation. Should there be a leak or build-up of these gases in a confined space this will deplete the level of oxygen and can pose a danger to employees and members of the public visiting your workplace. Employers have a duty of care to risk assess areas using inert gases and the O2NE+ is a simple and cost effective safety solution which could save lives.

The Analox O2NE+ main sensor unit is wall mounted at normal working head height in the area/s recommended as a result of a risk assessment (often where the gases are stored and/or piped). The repeater unit/s (which take their power from the main unit) are then sited at the entrance/s to the area to provide an early warning before entering.


Product FAQ's

Ask a Question

  • Can I adjust the alarm set points on my Analox O2NE+ Analyzer?
    Yes, please follow the instructions below. The procedure is very similar for setting either Alarm 1 or Alarm 2. 1) While the O2NE+™/Safe-Ox+™ is switched on, enter technician mode by pressing the mode switch 3 times. If entered successfully the green LED will flash off for 1.5 seconds and on for 0.5 of a second. 2) From technician mode, press the ‘Mode’ switch 2 times to set Alarm 1 or 3 times to set Alarm 2. The buzzer will bleep on each press. If this is done successfully, the instrument will show the ‘Fault’ indicator and the appropriate ‘Alarm’ indicator. If this is done inadvertently, or if another mode is selected, press the ‘Mode’ switch once to return to technician mode and then repeat this selection. 3) The display will indicate the present value of the alarm. 4) Press the ‘Mode’ switch twice to proceed to define a new setting, or once to abort and return to technician mode. 5) Press and hold the ‘Mode’ switch. The displayed value will count down at approximately one count per second. Release the switch when the displayed value is equal to the desired alarm value. 6) Upon release of the ‘Mode’ switch, the display will continue to show the new value. Accept the new setting by pressing the ‘Mode’ switch twice, or alternatively ignore the new setting by pressing the switch once. This will return to the technician mode. 7) To exit from technician mode, press the Mode switch once. The O2NE+™/SafeOx+™ then restarts by performing the normal power on sequence (4 flashes).
