The DG2 DetectaGas® CO Alarm Test Kit is an multi award winning carbon monoxide test kit designed to keep you and your loved ones safe. Carbon monoxide (CO) is a silent, invisible threat that can be deadly if undetected, which is why it is essential to ensure that all CO alarms are functioning properly.

The gas sensors fitted into CO alarms have a limited and undeterminable life and the test button does not fully test that the sensor is still sensing gas. Independent tests have shown that up to 45% of installed CO alarms are no longer sensing gas and up to 14% are not sensing properly out of the box.

Millions of CO alarms have been installed since 1995 but there is no regime which ensures that they are still working or removed and replaced once the sensor inevitably fails.

All CO alarms should be tested on installation and at least annually.

DetectaGas® offers a simple, safe and reliable way to properly test your carbon monoxide detectors, giving you peace of mind.

With its easy to use aerosol canister, DetectaGas® delivers a safe, no risk test gas which is held for the required period in the calibrated test shroud supplied in the lid of every kit allowing you to quickly verify that your alarms are sensitive and accurate, ensuring your home, caravan, mobile home, or workplace remains safe.
