TEMTS0250 - Tempilstik 250°F Temperature Indicator Crayon

The Welder's Choice for Accurate Heat Control

Achieve perfect welds and maintain structural integrity with the Tempilstik 250°F (121°C) Temperature Indicator. For professional welders, temperature control is not just a suggestion; it is often a requirement. Whether you are working on structural steel, pressure vessels, or critical piping, knowing exactly when your base metal has reached the required pre-heat temperature is essential to preventing hydrogen cracking and ensuring proper fusion. The Tempilstik 250°F provides a foolproof method to verify this temperature instantly, without the hassle of setting up expensive digital equipment.

Using the Tempilstik is incredibly straightforward. Simply stroke the workpiece during the heating process. As soon as the surface reaches 250°F, the dry, chalky mark will instantly transform into a distinct liquid melt. This visual cue is unmistakable and does not revert to its original appearance upon cooling, leaving a temporary record that the temperature was achieved. With an accuracy rating of +/- 1%, you can weld with confidence knowing that your pre-heat and interpass temperatures are exactly where they need to be to meet welding procedure specifications (WPS).

Durability is a major advantage of the Tempilstik over electronic alternatives. In the harsh environment of a welding shop—filled with sparks, dust, and electromagnetic interference—digital thermometers can fail or give erratic readings. The Tempilstik is immune to static electricity and requires no batteries or calibration, meaning it is always ready to work when you are. The included high-quality metal holder ensures the stick is used efficiently, allowing you to adjust the length as the stick wears down, maximizing the lifespan of the consumable.

This specific 250°F stick is widely used for a variety of applications beyond just pre-heating. It is excellent for monitoring post-weld heat treatment, annealing, and stress relieving processes. It is also a valuable diagnostic tool for checking operating temperatures of bearings, motors, and other machinery to detect overheating before failure occurs. Compact, reliable, and certified to meet major industrial codes, the Tempilstik 250°F is a must-have addition to every welder's toolkit. Ensure your work meets the highest standards of quality and safety with the industry's most trusted temperature indicator.
