One more question, what kind of thermometers are you guys using? Digital ones with K-type probe?Edit, would this work?http://www.ebay.com/itm/Digital-Thermometer-Meter-Tester-K-TYPE-Temperature-Probe-Hi-Resolution-TES1310-/251542128441?pt=LH_DefaultDomain_0&hash=item3a91144739
One thing to keep in mind, even though it is a K thermocouple the temperature rating of the probe material (insulation) may or will have a much lower max temp that the thermocouple wire.Tom
