The Tempil Tempilstik is a reliable temperature-indicating stick designed to quickly and accurately confirm when a surface has reached a specific temperature. Simply mark the surface before heating — the mark melts precisely at 650°F (343°C), giving you a clear, no-guesswork visual confirmation ideal for welding preheat, heat treating, and industrial thermal processes.
Compact and easy to use, the Tempilstik requires no batteries or calibration and delivers consistent results in demanding shop, maintenance, and manufacturing environments where accurate temperature verification is critical.
