Carbon monoxide is a particularly dangerous gas. It is colorless, it is odorless and above all it is lethal. That’s why it is so important that CO checks are carried out when a gas heating or boiler is being serviced or installed. This not only ensures that the heating or boiler is working properly; it also helps to prevent tragic accidents that occur as a result of carbon monoxide poisoning.

A few seconds. That’s all it takes. That’s all it takes to be on the safe side and test the surrounding air for carbon monoxide. The testo 317-3 CO detector measures the concentration of carbon monoxide in the surrounding air and presents the readings on an easy-to-read display. The CO detector has both a visual and an audible alarm which are triggered when a threshold is crossed. The thresholds can be adjusted individually.

The CO detector comes with a carry case and a belt clip to ensure that you always have your meter on you and a handstrap which can be wrapped loosely around the wrist to prevent the meter from falling onto the floor.

And as if that wasn’t enough, testo 317-3 CO detector also comes with a 3-year CO sensor warranty.
