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

· The CO/H2 null sensor does its best to completely nullify the effect of H2 on the CO sensor. In practice, a CO/H2 null sensor will typically have 1% or less H2 crossinterference. Going back to the example again, a standard CO sensor exposed to 100 ppm H2 would interpret it as 22 ppm CO. A CO/H2 low sensor exposed to 100 ppm H2 would interpret it as and display 5 ppm or less CO. The CO/H2 null sensor exposed to 100 ppm H2 would interpret it as and display 1 ppm or less CO.
