Accuracy of ET73?

    The last time I smoked some stuff I started wondering how accurate the ET73 was. I noticed that, according to the reading on the ET73 my fatty was done to temp, but it was still a little pinker than I wanted it. Then it did the same on a chicken.

    Today, I used a Taylor 1471N on my meatloaf while using the ET73 on the brisket. Obvioulsy, the meatloaf came to temp before the brisket so when it was done I tried a little science experiment. I put the probe of the Taylor near the probe of the ET73. As I am typing this the ET73 reads 165 and the Taylor reads 175. 10 degrees difference, but to my surprise (based on the last time) the Taylor says the meat is closer to done than the ET73. [​IMG]

    So, which one is right? Are there other factors that I am overlooking? Both probes are in equal depth in the same "thickness" of the brisket, very near one another but not touching.

    Any ideas, thoughts, comments, suggestions, insults? Is there a way to calibrate these things?

    Did you try setting the probes in boiling water, and ice water?  That should tell ya if there's a problem.

    I've never had a problem with my 73 but not saying it can't happen.

    they should read 212° and 32° plus or minus a degree or two.

    And be careful not to get the braided cable wet , I did once and it was shot

    I agree with Dan on this one and I test my thermos all the time. Just to keep them in check.

    I'll have to do that to check them. If it is off, would it be best to calculate how far it is off by a percentage?
