how often do you calibrate your thermometer

I'm wondering how often you calibrate your thermometer (dome that is)? I have the stock BGE thermometer that came with my large egg and I've calibrated it twice when it seemed a little off and was only off by a few degrees. I'm wondering what everyone else does? do you calibrate it on a regular basis or when you suspect something is wrong??


  • If it is the BGE thermometer: every month :(
    If it is a Tel-tru: never after checking it once :)

    I did mine when my egg was first new about 4 years ago now. Check it every Thanksgiving before the turkey goes on. It has been perfect for four years straight.

    Yep, once a month and gonna get some Tel Trus.

    Those stock ones have been off by 30+ every time I checkem. They currently are reading 150 (cold) air temp is about 80.
  • I've got 3 Tel-trus and they have never varied.

    I just stick the thermapen in the daisy for a minute. If I see it's off, I'll adjust it. Doesn't happen often.

    I've had 3 stock thermometers in 1.5 years. Once two of them went bad, I could not get them recalibrated. They would be calibrated at 212f but they stayed off below that and above that.

    I need to mail order a Teltru because no one carries them locally.

  • Once a month befor a low and slow cook. I took my temp gage off and attached the sprimg clip on and then shove it into the egg. It comes out easy and I can remove it if I have a large piece of meat in there and don't want to bend the probe. I close the lid then put the probe in the hole. During long cooks I will take out the dial thermometer and stick the maverick probe in the same upper hole.

    Little Steven-

    I just stuck my thermapen in the dasiy wheel and the
    temp on the thermapen kept going up and wouldn't stop I pulled it out at 400. my BGE thermometer says 300, could it be possible that i'm of 100 or am I doing something wrong with the thermapen?

    I'd bet your BGE is off that much. Thermocouple thermometers do drift, but not more than a few degrees. If they fail, it's in either shorted or open mode, and you can tell that pretty quickly.

    Thanks for your help. It's definitely the BGE thermometer. Will be calibrating tonight.

    This makes me feel much better about my boston butt disaster.
