  • 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 by the book 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.

    The testo 317-3 CO meter. For measuring carbon monoxide in the surrounding air

    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 tester measures the concentration of carbon monoxide in ambient air and presents the readings on an easy-to-read display. The CO meter has both a visual and an audible alarm which are triggered when a threshold is crossed.

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

    PLEASE NOTE: The Testo 317-3 is suitable to check Co in ambient air, Its however not suitable for measuring CO in discharged airstream.
