OVERVIEW

Precision Temperature Indication for Industrial Compliance

The Tempilstik 125°F (52°C) is the original temperature-indicating stick, an essential tool for industrial professionals who require absolute certainty in thermal processing. Manufactured by Tempil, a leader in surface temperature measurement, this product utilizes advanced phase-change technology to provide a distinct, irreversible melt point at exactly 125°F. For welding engineers, quality control inspectors, and metal fabricators, the TS125 serves as a primary method for verifying preheat temperatures, ensuring that base materials are properly conditioned before welding begins.

In critical applications such as structural steel fabrication, shipbuilding, and pressure vessel manufacturing, adhering to specific thermal parameters is not optional—it is a code requirement. The Tempilstik 125°F is engineered to meet the stringent demands of AWS D1.1, ASME Code Sec. I, III, and VIII, and ANSI/ASME Code B31.1. Its accuracy is rated at +/- 1% of the stated temperature, a level of precision that rivals electronic thermocouples but without the drift, battery failure, or calibration downtime associated with digital devices. Each stick is traceable to NIST standards, providing the documentation trail necessary for rigorous QA/QC audits.

The stick is housed in a durable, slip-resistant aluminum holder designed for industrial environments. The formulation is free of lead, sulfur, and halogens, making it safe for use on stainless steel, nickel alloys, and other sensitive metals where contamination must be avoided. Whether used for preheating, interpass temperature monitoring, or post-weld heat treatment, the Tempilstik provides an immediate, visual confirmation of temperature that is unaffected by static electricity or ambient interference.

FAQ

Simply stroke the workpiece with the Tempilstik during the heating process. When the mark left by the stick melts and turns into a liquid smear, the surface has reached 125°F (52°C).

The Tempilstik is accurate to within +/- 1% of its rated temperature, making it a highly precise tool for industrial applications.

No, the Tempilstik utilizes the fixed melting point of chemical compounds, which does not drift or require calibration like electronic devices.

Yes, standard Tempilstiks are typically free of lead, sulfur, and halogens, making them safe for use on stainless steel and other sensitive alloys to prevent contamination.

Once the mark melts at 125°F, it will remain liquid or char if the temperature continues to rise significantly, but the initial melt indicates the threshold was reached.

Yes, however, since 125°F is a relatively low temperature, it is more commonly used for initial preheat. For interpass monitoring, you would typically use a stick rated for the maximum allowable temperature.

It is generally good practice to remove the residue with a wire brush before welding over the area, although the formulation is designed to minimize weld contamination.

Yes, Tempilstiks are lot-numbered and traceable to NIST standards, which is often required for certified welding operations.
