Low cost handheld Oxygen monitor. Reliable and durable monitoring in a compact and long life package. Crowcon Gasman O2 has a sensor life in excess of 2 years. Oxygen can be depleted by the presence of other gases and can lead to death when critical levels are reached. Similarly high levels of oxygen, e.g. from ventilators and other medical applications can lead to high levels of oxygen which can be combustible. Our Oxygen gas meter alarms at recognised dangerous levels to protect you from gas exposure typically set at 19.5% for low oxygen and 23.5% for high oxygen.

NHS health chiefs in the UK have warned hospitals of the increased risks of “combustion” on the wards due to the higher number of ventilators being used to treat COVID-19 patients.

Our Crowcon O2 portable gas detector alarms at recognised dangerous levels, protecting patients and staff from high oxygen levels which can cause explosions as well as oxygen deficiency.

The long-life oxygen sensor delivers key features which provide real world tangible benefits to operator and site operations:

Industry’s first 5-year warranty

Industries are increasingly looking for cost-effective, sustainable, high quality investments and personal gas safety is no different.

Portables with the Long-Life O? sensor improve the fleet managers confidence and peace of mind that their Long-Life O? gas sensors will be operational for longer and protected under a 5-yearguarantee.

Lower cost of ownership

The new long-life Oxygen sensor helps gas detector fleet managers reduce down time and cost of ownership by increasing the O? sensor life to 5-years and reducing the number of replacement sensors required over the portable gas detector’s expected lifetime.

Service and Maintenance

CSL supply, service and maintain all our gas detectors in our workshop in Carlow or on site.
