Thanks for the thanks.
I actually bought another one a month or so ago. The problem is that the meter is so small and compact that I misplaced it somewhere. I expect it to turn up, so I will then have one for the toolbox that I carry in my car.
They are not only good for duty cycle, they are as handy as a pocket on a shirt and will probably fit in that pocket.
BTW, electrically measuring a thermocouple up to 1400 degrees is no problem, making a thermocouple that will live at 1400 degrees IS a problem. That's why the thermocouple they offer is only good for 500 degrees. Anything above that is to be run away from anyway.
Have a great day,
