The Tempil Tempilstik is a reliable temperature indicating stick designed to give you a quick, accurate visual confirmation that a surface has reached the required heat level. Simply mark the workpiece and the mark will melt precisely at 500°F (260°C), making it ideal for welding preheat, heat treating, and industrial process temperature verification.
Compact and easy to use, the Tempilstik requires no power source or instrumentation — just apply the crayon-style stick directly to the surface and observe the melt point. It is well-suited for metalworking shops, fabrication environments, maintenance and repair operations, and quality control applications.
