We stock Tempil's Tempilstik® product line in a range of temperatures. Tempilstik is the original temperature indicating stick with an excellent combination of precision, reliability and convenience. These "stiks" are specifically engineered to instantly melt at the designated temperature for accurate temperature indication in pre-heating, interpass and post-weld heat treating applications over a number of industries. Best of all, these guys are made in the U.S.A. We love that.
