Easy-to-install, wall mounted, modular carbon dioxide concentration monitor and warning alarm system, providing continuous monitoring of carbon dioxide concentration in the surrounding air and both visual and audible alarms when these fall outside pre-set levels.
The QFM440 Carbon Dioxide Monitor may be used as a stand-alone device with its own audible and visual alarms, or linked to other repeater modules to mimic the condition of the monitor. Repeater modules can be connected to the QFM440 and located outside the monitored area to warn users at the point of entry. The system can be fully customised to allow multiple location monitoring and further modules can be added at a later date to expand the scope of the system.
NB Carbon dioxide monitors must not be used for the detection of oxygen gas
