Overview
Carbon monoxide (CO) 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 heater or boiler is being serviced or installed. This not only ensures that the heater or boiler is working properly, but it also helps to prevent tragic accidents that occur as a result of carbon monoxide poisoning.
A few seconds. That’s all it takes to be on the safe side and test the surrounding air for carbon monoxide. The Testo 317-3 carbon monoxide monitor is perfect for a service technician to keep in a pocket or hooked onto a belt when working in environments that might have high levels of CO. The Testo 317-3 CO meter measures the concentration of carbon monoxide in the surrounding air and presents the readings on an easy-to-read display. The Testo 317-3 CO monitor has both a visual and an audible alarm which are triggered when a threshold is crossed. The thresholds can be adjusted individually.
To ensure accurate CO measurements an exclusive self-check can be performed to verify the CO sensor is working without the need to “zero” out the unit in fresh air. The Testo 317-3 ambient CO meter also includes programmable settings for both visual and audible alarms. When working in a noisy environment, the included earbuds are very helpful.
