Carbon dioxide is toxic and its levels should therefore be monitored using specific CO2 monitors, not O2 monitors.

Carbon Dioxide Monitors help to ensure a working environment is safe.  If levels become dangerous, the monitors will alarm.

A repeater unit does not monitor the carbon dioxide levels, but mimics the alarm on the carbon dioxide monitor.  Install a repeater unit outside the room to warn against entry.

Depending on the size of the room and the amount and type of cryogenic liquid stored, BOC Cryospeed has a range of carbon dioxide monitors and repeaters to fit most requirements.
