For personnel safety monitoring in:
Systems are available for Oxygen Enrichment Monitoring where the use of pure Oxygen either from bulk gaseous or liquid store, or on site generation is used for enriching air, perhaps for patient care or mixing with other gases for food packaging purposes – or where welding may present a safety or explosion risk.
The system for these applications can be set for alarm levels to be triggered if the Oxygen level exceeds the preset limit of 20.9% to 25%
Volt free contacts can be used to shut down the Oxygen supply ensuring the risk of explosion or fire is eliminated.
The product can measure up to twelve locations as standard with remote 4-20 mA oxygen sensors.
How many sensing points do I need?
The number of sensing points required to adequately monitor a space depends upon a number of factors.
Ox-An offer a full installation service. All that is required on site is the provision of a fused mains outlet
adjacent to the proposed location of the monitor and remote panel.
Service and Maintenance
OX-AN® Gas Detection Ltd offer a service contract providing a service visit at twelve monthly intervals. At the service schedule the electro-chemical Oxygen sensors are replaced and all the instrument’s functions and alarms are checked using test gases.
For intermediate system testing we can supply test gases in disposable canisters with a needle control valve and carrying case.
