The TEMPIL 24422 is a temperature indicating liquid used to verify surface temperatures during heating and heat-treating operations. Applied directly to metal or glass surfaces, it melts and leaves a visible mark when the surface reaches 700 degrees F (371 degrees C), giving technicians an immediate, reliable indication that the target temperature has been achieved. The formula dries fast on both horizontal and vertical surfaces and is designed to reduce settling in the container. Accuracy is rated within plus or minus 1 percent of the Fahrenheit target. The 2 oz container is a standard field size for HVAC, welding, and industrial maintenance work.
This temperature indicating liquid is suited for metalworking, brazing, soldering, and heat-treating applications where surface temperature verification is required. Compatible surfaces include glass and metal. It is commonly used by HVAC technicians, pipefitters, welders, and industrial maintenance professionals who need a simple, non-contact-free visual confirmation that a workpiece or component has reached the correct process temperature before or after applying heat.
Designed for use on glass and metal surfaces where surface temperature verification is required during heating, brazing, soldering, or heat-treating operations.
Apply a small amount of the liquid directly to the surface in the area to be monitored before or during the heating process. Allow the surface to reach temperature and observe the melt mark as confirmation. Shake or stir the container before use if settling has occurred. Follow all applicable safety protocols for hot work, including appropriate PPE when working near open flames or heated materials.
