Benefit from the protection of the fully featured O2NE+ Oxygen Level Monitor and alarm unit complete with a 7 year sensor life.

The use of inert and speciality gases is common in many medical applications including.

• Breathing observation – Asthma, Emphysema (Helium)
• Tissue preservation
• MRI rooms (Helium is used as a coolant for a superconductors in MRI machines)
• Cryopreservation (LN2 used for blood, sperm and egg preservation)
• Deep freeze – pathology
• Cancer treatment (Argon lasers)

Should there be a leak or build-up of these gases, which are both colourless and odourless, in a confined space this will deplete the level of oxygen and can pose a danger to employees and visitors your workplace.

The O2NE+ provides two audio visual alarms which are pre-set at 19.5% & 18% (but can be adjusted) to warn personnel of a potential leak which may cause the O2 levels to deplete to a dangerous level.

The O2NE+ main senor unit is wall mounted at normal working head height in the area/s recommended as a result of risk assessment. The repeater unit/s are then sited at the entrance/s to the area to let staff or visitors know if it is safe to enter or not.

Technical Specification

• Long life O2 sensor - Can last up to 7 years*
• Simple Calibration - The O2NE+ can be calibrated on "pure air" which is easy to source and ship globally and affordable too
• 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" - The O2NE+ is easily wall-mounted and basic installation does not require a qualified electrician
• Repeater Included - The O2NE+ comes complete a repeater which is to be placed at the entrance to provide and early warning before entering the room
• Suitable for use with helium - The 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 The 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.
