Tempil 24424 Temperature Indicating Liquid 800F 2 Oz

Product Description

The TEMPIL 24424 is a temperature-indicating liquid used to verify surface temperatures during brazing, welding, heat treating, and other thermal processes. Applied directly to glass or metal surfaces, the liquid dries quickly and melts at exactly 800 degrees F (427 degrees C), leaving a visually distinct mark that confirms the target temperature has been reached. Accuracy is within plus or minus 1% of the Fahrenheit rating and plus or minus 3% of the Celsius rating. The enhanced formula reduces settling and adheres reliably to both horizontal and vertical surfaces. Each container holds 2 fluid ounces.

This product is used across HVAC, plumbing, refrigeration, and metalworking applications where precise heat confirmation is required before or during soldering, brazing, or annealing operations. It is suited for use on glass, metal, and plastic substrates. Technicians apply a small amount to the workpiece before or during heating; the melt point provides a clear, reliable go or no-go indicator without the need for contact thermometers or infrared equipment.

Key Features

Compatibility

Designed for use on glass, metal, and plastic surfaces in thermal process applications including brazing, welding, soldering, and heat treating.

Installation Notes

Apply the liquid to a clean, dry surface at the desired temperature-check location prior to or during heating. Allow the coating to dry before beginning the thermal process. Keep the container sealed when not in use to prevent evaporation or settling. Installation and use of temperature-indicating consumables during gas or torch operations should follow applicable OSHA safety guidelines and local fire codes.
