TEMPIL 28310 TEMPILSTIK is a calibration‑free wax-based surface temperature indicator that melts precisely at 100 °C (212 °F), offering immediate visual confirmation when the threshold is reached. Designed for welding pre-heat, interpass monitoring, and post‑weld heat treatment, it ensures traceability with laser‑etched part number, melt temperature, and lot code. Reliable, portable, and compliant with AWS D1.1, ASME Sec. I/III/VIII, and ANSI/ASME B31.1/B31.3 standards. Made in the USA with over 80 years of industry trust.

  • Precisely melts at 100 °C / 212 °F with ±1 % °F and ±3 % °C accuracy—ensuring high consistency in temperature verification across surfaces. 

  • Instant visual indication: wax disappears cleanly at threshold—no tools or calibration required. 

  • Calibration-free & fully traceable: each stick is permanently imprinted with part number (28310), rated temperature, and lot code for audit compliance. 

  • Meets major welding/thermal codes: compliant with AWS D1.1, ASME Sec. I/III/VIII, and ANSI/ASME B31.1/B31.3 requirements. 

  • Portable and rugged design: compact ~0.625″ diameter wax stick housed in a slip-resistant metal holder for ease of use in field or shop environments. 

  • Versatile across materials: suitable for steel, stainless steel, aluminum, ceramic, glass, plastic, and more.
