What is an electrochemical carbon monoxide alarm?


  Electrochemical carbon monoxide alarms use zero- […]


Electrochemical carbon monoxide alarms use zero-power electrochemical carbon monoxide sensors as sensitive components, most of which use the principle of constant-potential electrolysis in electrochemical methods, and use constant-potential electrolysis to perform redox electrochemical reactions and detect diffusion current to obtain carbon monoxide. Gas concentration, and has a good linear measurement range and high selectivity, strong resistance to cross-gas interference, and the price is relatively expensive.

The electrochemical carbon monoxide sensor has zero power consumption and does not require heating. It is very suitable for battery-powered detection circuits with low power consumption to make carbon monoxide concentration meters, portable carbon monoxide alarms, etc. The long-term exposure of electrochemical carbon monoxide sensors to irritating solvents such as oxygen-free gas samples, alcohol, and paint will affect its sensitivity and life, or even fail.

The use of electrochemical carbon monoxide sensors in the air is generally three years, there are also five years, and the longer can be more than eight years.
