Testo 317-3 - CO Monitor

Carbon monoxide is a particularly dangerous gas. It is colourless, it is odourless 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.
