UEI analyzer CO ??

our company has 3 uei combustion analyzers. the oldest one is about 5years old the newest was purchased about 3 weeks ago. we have taken reading with all 3 at the same time in the flue. we get CO reading of 47ppm on the newest meter, the second oldest was about 44ppm, and the oldest was 99ppm. all meters have new filters and batteries. anybody run into similar issues?

    Yes

     I use two analysers, a UEI and a Bacharach. They are both good units, but each of them has been sent in for service 2-3 times. If your oldest one is off that much off from the other two, probably time. Kinda expensive too. I coulda bought two new ones for what it cost for six service fees. I hear Testo units can be repaired and calibrated by the user?

    Analyzers:

    So can the Bachrach Firite Insight. You can get into a program where they send you new sensors with a code and you install the new sensors and plug in the code for calibration.

    Calibrate them yourself

    Does anyone here get a bottle of test gas and calibrate them yourself?
