TEMPIL 28034 TEMPILSTIK is a high-precision, calibration‑free wax-based temperature‑indicating stick engineered to melt cleanly at 198 °C (388 °F). Designed for instant visual surface temperature verification during welding pre‑heat, interpass monitoring, and post‑weld heat treatment—it requires no electronics or gauges. Each stick is permanently laser‑marked with part number, rated temperature, and lot code to ensure full traceability. Complying with AWS D1.1, ASME Sec. I/III/VIII, and ANSI/ASME B31.1/B31.3 standards, this product is manufactured in the USA and trusted across heavy-duty industrial settings

  • Precise Melt Temperature: Melts exactly at 198 °C / 388 °F with ±1 % °F and ±3 % °C accuracy for reliable performance.

  • Instant Visual Confirmation: Wax completely disappears at threshold, providing clear visual feedback without tools.

  • Calibration‑Free & Traceable: Stick is fully marked with part number 28034, temperature rating, and lot code across its entire length.

  • Complies with Industry Standards: Meets thermal code requirements for welding and heat‑treat per AWS, ASME, and ANSI/ASME standards.

  • Rugged & Portable: Approximately 0.5″ length (0.625″ diameter typical) held in a slip-resistant metal sleeve for safe field use.

  • Versatile Surface Use: Effective on steel, stainless steel, aluminum, glass, ceramic, plastic, and more.
