Carbon Monoxide Alarm Cross Sensitivity – Hydrogen ...

· CO Detector. I have long been aware of the fact that electrochemical gas sensors have some cross-sensitivity, and sensors are available that are specifically designed to not respond to other gases (hydrogen in particular, as this gas is actually part of the sensor reaction. Much more information about the subject is over here). I’ve no doubt these more industrial grade sensors are much more ...

What is cross-axis sensitivity? | Murata Manufacturing Co ...

Cross-axis sensitivity is the maximum sensitivity in the plane perpendicular to the measuring direction relative to the sensitivity in the measuring direction. It is calculated as the geometric sum of the sensitivities in two perpendicular directions (Sx and Sy) in this plane. We appreciate your cooperation with the FAQ improvement questionnaire.

SPEC SensorTM

· an approximate 50% cross-sensitivity on the CO sensor; while CO exhibits virtually no response on the NO sensor. 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 …

Cross Sensitivity in CO Electrochemical Sensors - Testo

CO Sensor cross-sensitivity. The CO sensor responds to both CO and Hydrogen (H 2). Carbon Monoxide is type of gas which is commonly measured for any combustion application for tuning or environmental compliance. H 2 on the other hand is a combustion by-product of fuel degradation and is often found in combustion sources with low levels of oxygen in the exhaust. This means that in some ...

Testo Tech Notes: CO Sensor - H Cross Sensitivity 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. It is very possible that a sensor may respond to that target gas and ...

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

I guess my questions are, what causes cross sensitivity in a CO sensor, what is it sensitive to, and are there any data I could take a look at on the subject? Answer: Thanks for the great question! Sorry you are having problems due to the response of the CO sensors in your instruments to hydrogen. Substance-specific electrochemical sensors are available for many of the most common toxic gases ...

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.
