• The Wohler CM 220 is a pen style CO detector that is great for residential purposes like checking furnaces, room heaters, water heaters, and central heating furnaces. It can also be used in commercial settings to check the ventilation control of indoor parking garages. The electrochemical sensor gives a precise measurement even if other gases are present. The CM 220 also features a built-in alarm to warn you when the unit detects harmful levels of CO. This carbon monoxide gas detector displays the current reading and simultaneously displays the max value detected below. This CO carbon monoxide detector can easily be zero calibrated in an area free of carbon monoxide. To start calibration press the power and the backlight button at the same time for two seconds. The unit will blink "ppm" in the upper display and takes about 10 minutes to complete.
