The Tempil Tempilstik® 500°F (260°C) is the original and industry-leading temperature-indicating stick, designed to provide a simple, accurate, and reliable method for measuring surface temperatures in critical industrial environments. With a specific melting point of 500°F (260°C), this tool is essential for ensuring compliance with welding codes and heat-treating specifications.
Engineered for precision, the Tempilstik offers an accuracy of +/- 1% of its rated temperature. Unlike electronic sensors that require calibration, batteries, or complex setups, the Tempilstik utilizes the laws of physics—specifically the melting point of a formulated compound—to provide an immediate visual signal. When the workpiece reaches the rated temperature, the mark made by the stick instantly melts into a glossy liquid, providing a clear pass/fail indication.
This product is manufactured in the USA and is NIST traceable, making it suitable for use in industries requiring rigorous quality control, such as aerospace, shipbuilding, and power generation. It meets the requirements of major codes including AWS D1.1, ASME Code Sec. I, III, and VIII, and ANSI/ASME Code B31.1 and B31.3. The stick comes in a durable, slip-resistant metal holder with a pocket clip, ensuring it is always within reach on the job site.
Whether used for pre-heating steel before welding, monitoring interpass temperatures to prevent metallurgical damage, or verifying post-weld heat treatment, the Tempilstik 500°F is a trusted tool for quality assurance managers and fabrication professionals alike.
