The Ventec CM Carbon Monoxide Sensor measures levels in areas prone to a build up of CO gases – it is suitable for various applications, but is primarily designed for use in car park fume ventilation (2000-CP Mono Assist option).
The principle of the measurement cell used is based on the electro-chemical oxidation of carbon monoxide CO to carbon dioxide CO2 . The CO in the measurement air reaches the working electrode via a gas-permeable diaphragm, and is oxidised. The oxygen molecule used for this is replaced from the ambient air. This results in the very long service life of the measurement cell, which, from experience, can operate for several years.
The measured gas concentration is linear to the electrical output signal of the gas measurement probe. The potentiometers and the 3.5mm jack connection for the calibration are accessible from the outside, and permits a “one-man” calibration.
