Tempil 28070 Temp Indicating Stick 1700F

Product Description

The TEMPIL 28070 is a Tempilstik temperature indicating marker rated to 1700 degrees F (927 degrees C). It is used to verify surface temperatures during welding, heat treating, metalworking, and other thermal processes. The stick has a bullet-tip shape and works by melting instantly and visibly when the surface it contacts reaches its rated temperature. No calibration is required. Accuracy is within plus or minus 1 percent of the Fahrenheit rating. Welders, pipefitters, and metalworkers use this tool as a fast, reliable alternative to contact pyrometers or infrared thermometers when a quick visual confirmation of preheat or interpass temperature is needed.

The 28070 is suited for use on a wide range of substrate materials including aluminum, ceramic, glass, iron, plastic, stainless steel, and carbon steel. It is commonly used in structural welding, pressure vessel fabrication, pipe welding, and industrial heat treatment applications. The TEMPIL line covers 116 fixed-temperature increments from 100 degrees F (38 degrees C) to 2000 degrees F (1093 degrees C), allowing technicians to select the exact rating required by a welding procedure specification or heat treat protocol.

Key Features

• Rated at 1700 degrees F (927 degrees C) for precise go/no-go temperature confirmation
• Calibration-free operation with 100 percent reliability on every use
• Accurate to within plus or minus 1 percent of Fahrenheit rating
• Bullet-tip shape for controlled application to surfaces and weld joints
• Compatible with aluminum, ceramic, glass, iron, plastic, stainless steel, and steel substrates
• Single-use stick format — melts instantly at rated temperature for immediate visual confirmation

Compatibility

Designed for use on aluminum, ceramic, glass, iron, plastic, stainless steel, and steel surfaces. Suitable for any application requiring verified surface temperature at 1700 degrees F, including preheat and interpass temperature checks in welding and heat treatment processes.

Installation Notes

Applied by welders, pipefitters, and heat treat technicians directly to the workpiece surface before or during thermal processing. Mark the surface away from the direct flame or arc zone and observe for the characteristic melt indication. Follow applicable welding procedure specifications and applicable codes such as AWS D1.1 or ASME Section IX for required preheat and interpass temperature ranges. Store markers away from heat sources to prevent premature softening.
