? Accuracy of Maverick ET-73

    I just received the ET-73 and upon reading the info and "putting things together" (very little), I am finding that the probes are reading about 7-8 degrees to high and there is a 5 degree difference in the "cooker" probe and the "food" probe. Is this common, and do I just need to find out through the boiling water check, what adjustment to make when smoking ? I guess I could then create a "conversion" chart to use. Any suggestions or fixes would be appreciated.

    Yeah, that's normal. Do the boiling water check to calibrate it properly.

    ...and keep in mind that higher elevations will reduce the boiling temp of water.

    Here's some detailed info on boiling points at altitude/elevation, including a conversion chart to determine what the boiling temp should be based on your elevation:


    Happy smokes!

    I just ran a cal on the 4 digital probes i have. I took them all (4) and twist tie them together about 2/3 way up and "stirred" then in the boiling water got 206 on all of them.
    Why 206 well i am at 3500ft..
    most digital probes do not have a "adjustment" as they are control electronically.

    Yeah, you can't adjust them, you just adjust your interpretation of what they read. ;)

    Yours should actually read about 205*, smokey paul, so that's pretty close.

    Thanks for the info. What about on the bottom end ? Do we have to check the freezing or near freezing temp. for accuracy too or just assume it will be off by the same amount as the boiling point is.?
