"In the instructions, it says that this meter will measure up to 1400 degrees F. The only thermocouples that I see in the Sears site only go to 500 deg. Am I missing something? I may want to measure my BBQ grill fire or something."
At the Cole-Parmer website you can find several models of probes, from basic to fancy, that will go to 1400F. One at just under $40 looks real nice, one at $22 is much more basic, but still immersible and food-safe. Most type-K thermocouple wire is teflon insulated (500F) and the high-temp models insulate in the probe with ceramic standoffs, SS for the sheath.
