Tempilstik 66 C / 150 F

Providing accuracy, confidence and compliance for over 80 years, Tempilstik is the original temperature-indicating stick with the best combination of precision and convenience for surface temperature measurement. Specially engineered for accurate temperature indication in pre-heating, interpass and post-weld heat treating applications, Tempilstik is the industry’s leading choice for use in the most critical jobs.  Please note that the color of the Tempilstiks are not a part of their function, since the temperature signal consists of melting.  Indicator color is subject to change without notice.
