Carbon Monoxide Sensors | CO Sensor | Alphasense

Carbon Monoxide Gas Sensors. Carbon monoxide (CO) is a particularly dangerous toxic gas, not only because it has no colour, no taste and no odour but because it is common in populated areas as a result of the burning of fossil fuels in vehicles and heating systems.


Carbon Monoxide Sensors: How Do They Differ and Why Does ...

May 28, 2021· Let’s do the math: If a CO sensor that is not a CO/H2 low or CO/H2 null sensor is exposed to 100 ppm of H2, the sensor would interpret the 100 ppm of H2 as 22 ppm of CO. This is based on the CO sensor’s crosssensitivity to H2. A CO/H2 low sensor typically has 5% or less H2 gas crossinterference. Referring to the example above, a standard ...


CrossContamination of Sensors by Other Gases and …

target gas is called its crosssensitivity. Figure 2 shows the crosssensitivity of one carbon monoxide sensor to other gases both with and without a filter and after the sensor has been allowed to age. Most gases like propane, butane, ammonia, and nitrogen dioxide have very little effect on the readings of this carbon monoxide sensor.
