Does the CO sensor have a crosssensitivity to H2?

+

Up to15%cash back· The electrochemical CO sensors used in the majority of our products do have a crosssensitivity to elemental hydrogen (H 2) gas, with the precise degree of crosssensitivity depending on the model in those applications where the CO monitoring is necessary in the presence of H2, models with COH sensor would be the best option.

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

+

May 28, 2021· 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 CO sensor would interpret and display 22 ppm of CO if 100 ppm of H2 was present in the environment.

Why is hydrogen such a big issue for CO sensors? | GfG ...

+

Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%. (Not GfG sensors, of course!) Sometimes the cross sensitivity is presented as an advantage to customers.
