co sensor cross sensitivity

SPEC SensorTM

Mar 24, 2015· By including an NO sensor in the detector, the CO readings can be automatically compensated for the measured NO. ii. Applications where it is desired to measure two or more gases for which both sensors exhibit cross-sensitivity to the other gas. Example: measuring O3 and NO2 in the air: These sensors both exhibit cross-sensitivity to the other gas.

Testo Tech Notes: CO Sensor - H Cross Sensitivity 2

CO Sensor - H 2 Cross Sensitivity CO Sensor H2 Cross Sensitivity White Paper Gas measurement is a sophisticated science that, done right can provide very accurate results or done wrong can lead to costly misdirection. Sensors that are intended to measure single gases may respond erroneously if they are not controlled or conditioned properly.

Does the CO sensor have a cross-sensitivity to H2?

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

What are Hydrogen Compensated CO Sensors? | Kane ...

The CO sensor used on the KM900 and KM9106 is specially designed to eliminate the effects of hydrogen cross sensitivity. The sensor contains an extra electrode that allows the effect of sensitivity to hydrogen to be counteracted within the electronics. So as well as the sensor being calibrated using a certified carbon monoxide test gas it is ...

Application Solution Understanding Cross-Sensitivities

MOS sensors, unlike Catalytic or Electrochemical sensors, do not product a linear response. Due to the nature of this reaction, MOS sensors produce an exponential response to the gas applied. Therefore, to understand cross-sensitivity, a curve is needed for an accurate comparison. A sensor calibrated to R134A responds more drastically to

SENSOR SPECIFICATIONS AND CROSS-SENSITIVITIES

NO, instead of 25 ppm. A CO sensor used to measure 100-1,000 ppm hydrogen should be calibrated with 1,000 ppm hydrogen gas. Calibration Flow Rate: Recommended calibration gas flow rate. Cross-Sensitivity: Every sensor has some cross-sensitivity, where the sensor responds to other gases that are not filtered out and can react on the electrode.
