Curiosity Question For Jim Davis

The sensors are not subject to RH, but to the gas they are sensing. They are chemical sensors, and when the reaction stops, the chemical is no good anymore. Simply, it is used up. O2 sensors start going bad the day they are installed and CO sensors the like. The sensors are getting better though, the Testo 330-ll has a life of 4 years and typically a tech can squeeze 5 out of it. The major thing is not to over range the CO cell.

    We all know,

    CO sensors in an analyzer must be replaced every couple of years depending on the manufacturer, because of its usage/intake.

    But if a controlled environment was attained (via a vacuum pump to 30") for a given length of time would this not re-new the component? Are they not suspect to humidity infiltration?

    Just curious,, but I wonder how this can even be manufactured unless they came from the space shuttle in vacuum packed bags.

    Could we have all been deceived?
