Carbon monoxide is a particularly dangerous gas. It is colourless, odourless and above all lethal. The 317-3 CO meter from Testo measures the concentration of carbon monoxide in the surrounding air and presents the readings on an easy-to-read display. This meter has both a visual and an audible alarm which are triggered when a threshold is crossed. The thresholds can be adjusted individually. What's in the box?
