Tempil 350F/177C Tempilstick Temperature Indicator (TEMTS0350)

The Tempil 350°F/177°C Tempilstick Temperature Indicator provides accurate surface temperature measurement for critical welding and heat treatment applications. This temperature-indicating crayon melts precisely at 350°F, offering welders and fabricators a reliable method to monitor preheating, interpass temperatures, and post-weld heat treatment processes. Simply mark the surface and observe when the indicator melts to reach target temperature. Essential for ensuring proper welding procedures and meeting code requirements in structural and pressure vessel work.
