TEMTS0425 - Tempilstik 425°F (218°C) Surface Temperature Indicator Stick

Reliable 425°F Temperature Indication for Welding Professionals

Achieve perfect thermal control in your welding and fabrication projects with the Tempil Tempilstik 425°F (218°C). This temperature indicating stick is an essential tool for any welder's kit, offering a quick, easy, and highly accurate way to measure surface temperatures. In the high-stakes world of welding, guessing the temperature of your base metal can lead to catastrophic failures. The Tempilstik eliminates this risk by providing a clear, instant visual signal when the metal reaches exactly 425°F. The dry, chalky mark transforms into a glossy liquid melt the moment the threshold is crossed, a change that is easily visible even through a welding helmet or in low-light conditions.

The Tempilstik 425°F is particularly valuable for monitoring pre-heat and interpass temperatures, which are critical for controlling cooling rates and preventing the formation of brittle microstructures in high-strength steels. Its simplicity is its greatest strength; there are no batteries to die, no sensors to break, and no complex menus to navigate. You simply stroke the surface during heating, and the stick tells you exactly when you are ready to weld. This makes it an invaluable tool for both seasoned professionals and apprentices alike, ensuring consistency across every weld pass.

Built to withstand the harsh realities of the job site, the Tempilstik is encased in a high-quality metal holder that prevents the crayon from snapping and allows for maximum usage of the material. It is immune to static electricity and interference that can plague digital thermometers. Furthermore, the Tempilstik is an economical choice, offering hundreds of readings per stick at a fraction of the cost of electronic alternatives. With its NIST-traceable accuracy and robust formulation, the Tempilstik 425°F ensures that your heat treating and welding processes are executed with precision and confidence every time.
