TEMPIL
275°F Temperature Indicating Stick, Calibration-Free Welding Crayon
Item #:
TS0275
MFR #: 28023
Product Details
The Tempil Tempilstik 275°F Temperature Indicating Stick is the original temperature-indicating crayon built for precise surface temperature measurement in welding and metal fabrication. It melts instantly at the designated 275°F (135°C) temperature point, leaving a distinct, easy-to-read mark for immediate visual inspection with no calibration required. NIST-traceable accuracy of ±1% Fahrenheit meets the requirements of AWS D1.1, ASME Code, and ANSI/ASME preheat standards. Densely constructed for long life, each stick is free of sulfur, lead, and halogen contaminants and works on steel, iron, aluminum, stainless steel, glass, plastic, and ceramic surfaces.
- Melts instantly at the rated 275°F (135°C) surface temperature for fast, clear visual confirmation with no guesswork
- Calibration-free with NIST-traceable ±1% Fahrenheit accuracy — certifiable for nuclear use and critical weld inspections
- Complies with AWS D1.1, ASME Code Sec. I, III and VIII, and ANSI/ASME B31.1/B31.3 preheat and interpass temperature requirements
- Densely constructed crayon delivers more than 11,000 six-inch marks per stick for outstanding value over time
- Free of sulfur, lead, and halogen contaminants — exceeds industry contamination standards for sensitive base metals
- Works on steel, iron, aluminum, stainless steel, glass, plastic, and ceramic surfaces across a wide range of applications
- Made in the USA; ideal for preheating, interpass monitoring, annealing, stress relieving, and post-weld surface heating
