| Post subject: | Induction and Thermapen |
Hi folks, I’ve been lurking over here for a while, but haven’t had much to say. It’s great to see all the familiar names. I have had an Induction Cook Top for a while now and I love it. I don’t have any problem that needs your help. I just have a “curious thing” that I thought some of the experts might have an idea about. My Thermapen will not work when the pan is on the stove or even close to the burner. Not even to check temp of liquids. All of my other thermometers work normally. My cook top is a Bosch, but I also have a Circulon portable burner that does the same, so it’s the something about the Thermapen. Any ideas? Jim |

The induction cooktop works by radiating an electromagnetic field that induces electrical currents in the cookware, making the cookware heat up. Apparently enough of the electromagnetic field gets past the pan to get to the Thermapen and interfere with its operation. The probe length of the Thermapen may help by being sort of an antenna relative to the wavelength og the EM radiation. What about your other thermometers? Are they electronic? Is the probe physically close to the display electronics? Can you change whether the Thermapen is affected by changing its orientation relaitve to the cooktop? It might be worth a call to Thermoworks to see if they are aware of any issues with induction cooktops and the Thermapen. |

Thanks for the quick reply. I agree with your thoughts. It doesn't seem to matter about the orientation of the Thermapen. The only other electronic thermometer that I have is the CDN Programmable Remote Probe which I do not normally use on the stove top, but it will work. The readout portion is obviously not close. That could be the difference. I may call Thermoworks just out of curosity. The stove has touchpad controls and is very quick, so if I don't want to move the pan off the burner and need a quick read, I just touch "0" on the controls, get the readout and go back to the desired setting. Mostly comes up with a chicken breast or the like. |

Jim I have a question for you about induction cooking...most of my pots and pans are All Clad, MC 2 (brushed stainless on the exterior). When I was working at Sur La Table, someone mentioin that that version of All Clad will not work on an induction cooktop. Do you (or anybody else) know if that is correct? ilene |

I have not owned any MC2. Only stainless in the AC. If a magnet sticks to it, then you are in business. I thought that I remember reading that MC2 would not work, but I am not sure. Jim |

I am curious to see what Thermapen says... I have induction too and was thinking of getting one. Ilene, I love my induction... do the magnet test like Jim says. Mary |

Thermoworks said that appreciated the call and that were not aware of this. They explained that Thermapen works by reading voltage and most other thermometers that I might use work by resistance. So the theory is that The electromagnetic field created on the induction hob effects the voltage reading. I think that is sort of what was said. I may not have it technically correct, but close enough for a lay person. He had another deep explaination as to why the CDN probe would work. I asked about their probe thermometer and he said that he wasn't sure. I suggested that if they send me one that I would "field test" and report back. They are going to discuss and call back. I will keep you informed. Jim |

My answer to the question about AC MC2 being induction ready should have been no. MC2 has a brushed aluminum exterior so it will not work. Sorry I didn't answer correctly the first time. Jim |

Thanks Pete. I knew I came to the right place to get some answers. I can't believe that Thermoworks hasn't called about testing for them.LOL |
