TEMPIL

TEMPIL is a brand historically associated with temperature-indicating products used to verify surface temperatures in industrial processes. The product line includes temperature-indicating markers, often called temperature indicator sticks or crayons, and temperature-indicating liquids, sometimes referred to as temperature-indicating paints or lacquers. These products are designed to change state or appearance at a specific rated temperature, providing a visual indication that a surface has reached that temperature. TEMPIL products are commonly used in welding preheat and post-weld heat treatment, heat treating, metalworking, and machinery maintenance, where confirming that a material has reached a target temperature is critical for process control and quality assurance.

About TEMPIL

TEMPIL is a brand historically associated with temperature-indicating products used to verify surface temperatures in industrial processes. The product line includes temperature-indicating markers, often called temperature indicator sticks or crayons, and temperature-indicating liquids, sometimes referred to as temperature-indicating paints or lacquers. These products are designed to change state or appearance at a specific rated temperature, providing a visual indication that a surface has reached that temperature. TEMPIL products are commonly used in welding preheat and post-weld heat treatment, heat treating, metalworking, and machinery maintenance, where confirming that a material has reached a target temperature is critical for process control and quality assurance.

The temperature-indicating markers are supplied as stick-type markers in a 3 fl oz size. They are available in a range of rated temperatures, with examples including 125°F, 150°F, 275°F, 325°F, and 600°F. Accuracy for these markers is typically specified as either ±1% F or ±3% C, depending on the specific product. The markers melt at their rated temperature, leaving a visible mark that indicates the surface has reached that temperature. This method is used for preheat verification, interpass temperature monitoring, and other applications where a simple, direct indication is required.

The temperature-indicating liquids are supplied in 2 fl oz containers and are available in rated temperatures such as 350°F, 500°F, and 700°F. Accuracy for these liquids is specified as ±1% F or ±3% C, depending on the product. The liquids change appearance, such as drying to a different color or consistency, when the rated temperature is reached. They are applied to surfaces and are used in similar applications to the markers, including welding preheat, heat treating, and maintenance operations. The liquids can be used on complex geometries or where a larger area needs to be monitored.

3G Electric supplies TEMPIL temperature-indicating markers and liquids as part of its industrial equipment portfolio. The products are available with manufacturer part numbers such as 28005, 28006, 28023, 28029, 28047, 24408G, 24416, and 24422. 3G Electric supports the line by providing access to these products, along with logistics and order fulfillment for customers worldwide. Technical buyers can reference the rated temperature, accuracy, and container size when selecting the appropriate product for their specific process requirements. The product family covers a range of temperatures from 125°F to 700°F, allowing users to choose the indicator that matches their target temperature. The markers and liquids are consumable items used in quality control and process verification, and they are typically purchased in quantities that reflect ongoing operations. 3G Electric can provide quotes and availability information for the TEMPIL products listed in its catalog.

Common Applications

  • Welding preheat — TEMPIL temperature-indicating markers (e.g., MPN 28029, 325°F) verify base metal temperature before welding.
  • Post-weld heat treatment — TEMPIL temperature-indicating liquids (e.g., MPN 24416, 500°F) confirm that the required temperature has been reached.
  • Heat treating — TEMPIL temperature-indicating markers (e.g., MPN 28047, 600°F) monitor surface temperature during heat treatment processes.
  • Metalworking — TEMPIL temperature-indicating liquids (e.g., MPN 24422, 700°F) provide visual confirmation in metal fabrication operations.
  • Machinery maintenance — TEMPIL temperature-indicating markers (e.g., MPN 28005, 125°F) check surface temperatures during maintenance and repair.
  • Quality control — TEMPIL temperature-indicating products (e.g., MPN 28023, 275°F) are used to verify thermal processes in manufacturing.

Frequently asked questions

Common questions about TEMPIL from 3G Electric.

What is the difference between TEMPIL temperature-indicating markers and TEMPIL temperature-indicating liquids?

TEMPIL temperature-indicating markers are stick-type products, typically 3 fl oz, that are applied directly to a surface. They melt at a specific rated temperature, leaving a visible mark to indicate that the surface has reached that temperature. TEMPIL temperature-indicating liquids are supplied in 2 fl oz containers and are applied to a surface, where they change appearance when the rated temperature is reached. Both types provide a visual indication and are used in applications such as welding preheat and heat treating. The choice between them depends on the surface geometry, the area to be monitored, and user preference.

What temperature range is available in TEMPIL temperature-indicating markers?

TEMPIL temperature-indicating markers are available in a range of rated temperatures. Examples from the 3G Electric catalog include 125°F (MPN 28005), 150°F (MPN 28006), 275°F (MPN 28023), 325°F (MPN 28029), and 600°F (MPN 28047). Accuracy is specified as either ±1% F or ±3% C, depending on the specific product. The markers are supplied as 3 fl oz sticks. For a complete list of available temperatures, refer to the product listings or contact 3G Electric for assistance.

How accurate are TEMPIL temperature-indicating liquids?

TEMPIL temperature-indicating liquids are specified with an accuracy of either ±1% F or ±3% C, depending on the product. For example, the 700°F liquid (MPN 24422) has an accuracy of ±1% F, while the 350°F liquid (MPN 24408G) has an accuracy of ±3% C. These accuracies indicate the tolerance around the rated temperature at which the liquid will change appearance. The liquids are supplied in 2 fl oz containers and are used for visual confirmation of surface temperature in processes such as welding preheat and heat treating.

What are typical applications for TEMPIL temperature-indicating products?

TEMPIL temperature-indicating markers and liquids are used in applications where it is necessary to verify that a surface has reached a specific temperature. Common uses include welding preheat, post-weld heat treatment, heat treating, metalworking, and machinery maintenance. In welding, they help confirm that the base metal has reached the required preheat temperature before welding begins. In heat treating, they can be used to monitor that a part has reached the desired temperature. The products provide a simple, direct visual indication without the need for electronic instrumentation.

What sizes are TEMPIL temperature-indicating markers and liquids available in?

TEMPIL temperature-indicating markers are supplied as 3 fl oz sticks. TEMPIL temperature-indicating liquids are supplied in 2 fl oz containers. These sizes are consistent across the examples in the 3G Electric catalog, including markers with MPNs 28005, 28006, 28023, 28029, and 28047, and liquids with MPNs 24408G, 24416, and 24422. The container size is specified in the product description and can be used to estimate the number of applications per unit.

Can TEMPIL temperature-indicating products be used on any surface?

TEMPIL temperature-indicating markers and liquids are designed for use on surfaces where a visual indication of temperature is needed. They are commonly applied to metals and other materials used in welding, heat treating, and maintenance. The product should be applied according to the manufacturer's instructions, which typically include cleaning the surface and applying the marker or liquid in a representative area. The rated temperature and accuracy are specified for the product, and the indication occurs when the surface reaches that temperature. For specific material compatibility, refer to the product documentation or contact 3G Electric.
