Can a carbon monoxide detector double as a propane gas ...

Jun 17, 2012· Usually, “detector” means the sensing element within the instrument. But, people sometimes refer to the entire instrument as the detector. Now, if the sensor for carbon monoxide also responded to propane, this would not be desirable, as the propane would represent an interference, and cause errors in the CO measurement.

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

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. 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%.

Where should I place a carbon monoxide detector? | Indoor ...

Jul 15, 2020· Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flameproducing appliance. Keep the detector out of the way of ...

Understanding Cross Sensitivities Can Help Keep Workers ...

May 01, 2018· Ideally, a user would want a carbon monoxide (CO) sensor to only read carbon monoxide, but there are other gases that can generate readings on this sensor. This is just one example of many cross interferences. We can slow this reaction down with the use of filters on the sensors, but yet again, it does not eliminate the reaction.

The scavenger corrects this by either catalyzing the oxidation of carbon monoxide to the less competitive carbon dioxide or immobilizing the carbon monoxide by affinitytype or covalent binding. Analogous effects are achieved for analytes other than nitric oxide but that likewise encounter interference from carbon monoxide in binding to sensors.

Solidstate Electrochemical Gas Sensor: Carbon Monoxide ...

Carbon monoxide (CO) is produced as a poisonous gas. As CO levels increase and remain above 70 ppm, symptoms become more noticeable and can include headache, fatigue and nausea. At sustained CO concentrations above 150 to 200 ppm, disorientation, unconsciousness, and death are possible. This Smoke100 sensor measures CO level below 100 ppm ...
