Wohler CM220 CO Meter
The Wohler CM220 is perfect for the measurement of CO in ambient air and is most commonly used during the installation and maintenance of gas boilers or heating systems. Carbon monoxide is lethal in high concentrations so it is wise to be aware of the conditions you are working or living in.
Key Features:
- 0 to 999 ppm
- Electrochemical Sensor
- Displays current and max reading simultaneously
- Backlight
- User Calibratable
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.
