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.
