GSE Detectagas DG1 CO detector test aerosol (250ml) for testing of CO detectors. Designed to test CO detecting, ceiling mounted fire alarms in combination with the aersol dispenser DH1 Detectahead. Not suitable for conduct tests on domestic CO alarms

The Detectagas® 250ml CO DG1 is intended for testing ceiling mounted fire detecting CO alarms and is designed to be compatible with most aerosol dispensers. The activation point for fire detecting CO alarms is very low compared to domestic CO alarms and is immediate rather than delayed. The CO level in DG1 is therefore very low and not suitable for testing domestic CO alarms.
