    I replaced the obiwgen sensor and calibrated calibrated O2
    I got some 20ppm CO calibration gas and calibrated the CO sensor, as my COOTWO read CAL in the CO display
    Three days later I flew to Egypt on a LOB
    Wien I tried to test my. first tank the CO reading read? Replace sensor.
    Why die IT accept calibration three days earlier?

    CO calibration expires every 12 months
    CO life time is ~2 years.

    Did you check for CO lifetime expiration before calibrating it?

    No, I did not, how can I check CO lifetime expectation?

    You can only check the last recorded sensor replacement date. I think it is in the same part of the app that shows calibration history.

    It does not estimate the life remaining. Once it reaches replacement date + 24 months, it marks the sensor as expired.

    If you go to the CO sensor replacement screen the app will tell you when the CO sensor should be replaced.
