Gas Alarm

Ax60+

Multi-gas CO₂ & 0₂ Safety Monitor

Gas Alarm

The Ax60+ is a wall-mountable, multi-gas safety device for monitoring carbon dioxide and oxygen. Based on the popular Ax60 CO2 detector, the new Ax60+ can also be supplied with O2 sensor modules which provides an early warning of both oxygen depletion and oxygen enrichment. The CO2 and O2 sensors are interchangeable and can be fully integrated as part of a multi-point, multi-gas detection and alarm system.

The CO2 sensor is set by default to trigger a low-level alarm at 1.5% CO2, an evacuation alarm at 3% CO2 and a time-weighted average alarm of 0.5% CO2 measured over eight hours. The O2 sensor is set by default to trigger low-going alarms at both 19.5% and at 18% and a high-going alarm at 23%. The alarm setpoints can be changed by the user. Warnings are announced by high-visibility strobe lights and high-volume sounders.

O₂NE+

Oxygen Depletion Monitor

Gas Alarm

The O2NE+ is a simple to use and maintain ambient oxygen depletion monitor and sensor, ideal for monitoring oxygen levels where inert gases such as N2, Ar or He pose a risk of depleting O2 levels in ambient air.
It comprises of a wall mounted main sensor unit and a repeater. It is ranged from 0 to 25% O2 and has 2 audio/ visual alarms. The sensor is long life and calibration adjustment is only required once the unit is initially installed and following a cell replacement and can be achieved using certified air*. We recommend a proof test is carried out every 12 months. The instrument uses an electrochemical cell together with state of the art technology, built in an IP65 splash proof housing and is designed to provide long, trouble free service, with minimum maintenance. The O2NE+ has two pre-set alarm levels at 19.5% and 18% O2. The oxygen sensor used is not cross sensitive to helium so will measure correctly in the presence of a helium atmosphere. This means that the sensor can be safely used to detect oxygen displacement by helium gas leaks.
The O2NE+ is installed in areas where an inert gas is being used or stored to provide a warning should the oxygen levels deteriorate to an unsafe level. The repeater is located at the entrance to the room, highlighting the danger to personnel before they enter.
* The O2NE+ is a precision instrument and needs to be handled with care

Safe-Ox+

Oxygen Depletion & Enrichment Monitor

Gas Alarm

The Safe-Ox+ is an ambient oxygen enrichment and depletion monitor which is simple to use and maintain.
The Safe-Ox+ consists of a wall mounted main sensor unit and a repeater. It is ranged from 0 to 25% O2 and has 1 low and 1 high audio/visual alarm. The sensor has a long life and calibration adjustment is only required once the unit is initially installed and following a cell replacement and can be achieved using certified air*. We recommend a proof test is carried out every 12 months.
Industries that store and operate with high levels of O2 need to detect and monitor the levels of oxygen - should there be a leak of enriched O2 this could prove to be a fire risk. Enriched oxygen is used in a variety of industries and applications such as: commercial dive systems, hyperbaric oxygen therapy (HBOT), gas production and gas blending stations, medical and laboratory gases such as nitrous oxide/oxygen mixes, sulphuric and nitric acid manufacture, mining, steel manufacture and metal refining, aquaculture and glass manufacture. The Safe-Ox+ provides a high O2 alarm ideal if you are using pure oxygen, to protect you from O2 enrichment. If there is a leak or build up of inert gas such as nitrogen, argon or helium the Safe-Ox+ can also warn of oxygen depletion. The Safe-Ox+ can be wall mounted at normal working head height in the gas storage room, or where enriched O2 is piped. The unit comes with one repeater as standard which is located at the entrance to the room. The Safe-Ox+ has an integral pressure sensor that allows the device to automatically compensate for local pressure changes.
