I forget the brand we use now, but much cheaper. Rather than paying to have it calibrated annually, toss it and buy another one. For what it's worth, we aren't allowed to use infrared guns for heat treating purposes. I don't know if an infrared gun can be calibrated or not. Even the stop watches used have to be calibrated annually. These same engineers (materials engineers) have stated for the record cast iron is a non-weldable material. I'm sure it's for liability purposes, but there it is. [Reply]   [No Email]

That"s as far as I can go with it. Whenever we pre/post heat or stress relieve, we have to collect and store the data, and graph the process from start to finish. That can be accomplished easily with thermocouple connections. I"ll bet a dollar we can get a vise up to 1200 + degrees in under a minute and prove it with some old school Miller powered induction heaters. Scary how fast that system is. [Reply]  [No Email]
