The Tempilstik is a crayon-style temperature indicator for welding, fabrication and maintenance work. You mark the heated metal; the stick melts at its rated temperature, giving an instant visual check that the part reached preheat or interpass heat. Tempil offers 116 ratings from 100°F to 2,000°F, each stick imprinted with its temperature and lot code for traceability, and the melt-point accuracy is rated to about ±1% in Fahrenheit. It meets the preheat requirements of AWS D1.1 and ASME codes, which is why it is common in pipe, rail and shipyard work. Rivals include digital infrared thermometers and contact probes: those read a number, while a Tempilstik only confirms a threshold, but it needs no battery, no calibration and works on curved or awkward surfaces.

Buyers describe the Tempilstik as easy to use and working as expected for preheat and temperature checks. Feedback is thin, with at least one one-star rating among the reviews.
The Tempilstik is a temperature indicating stick used to check whether a surface has reached a set temperature. This version is rated for 1,000°F. When the heated surface reaches that temperature, the mark made by the stick melts, which gives an immediate visual check.
The stick needs no calibration. It is accurate to within +/- 1% of Fahrenheit and +/- 3% Celsius rated. The part number, temperature and lot code are imprinted along the entire stick for traceability.
Tempilstik is used on aluminum, ceramic, glass, iron, plastic, stainless steel and steel. Its applications include welding and metal fabrication, oil and gas production, railroad, ship building and repair, and transmission work. It complies with the preheat temperature requirements of AWS D1.1, ASME Code Sec. I, III and VIII, and ANSI/ASME Code B31.1 and B31.3.
