OVERVIEW

Precise Temperature Indication for Industrial Applications

The Tempil Tempilstik 550°F (288°C) is the industry-standard temperature indicating stick, designed to provide a simple, accurate, and reliable method for measuring surface temperatures in critical industrial environments. Leveraging the laws of physics, the Tempilstik utilizes a phase-change technology where the stick material melts once the workpiece reaches the specific rated temperature of 550°F. This distinct solid-to-liquid transition offers an immediate visual confirmation that the target temperature has been achieved, eliminating the ambiguity often associated with color-change indicators or electronic sensors that may require calibration.

Engineered for precision, the Tempilstik offers an accuracy of +/- 1% of its rated temperature, making it a trusted tool for quality control and compliance with stringent welding codes such as AWS D1.1, ASME Section I, III, and VIII, and ANSI/ASME B31.1 and B31.3. It is particularly valuable for pre-heat, interpass, and post-weld heat treatment (PWHT) monitoring, ensuring that materials are processed within their specified thermal windows to prevent cracking, warping, or metallurgical defects.

The stick is housed in a durable, slip-resistant metal holder equipped with a pocket clip, ensuring it is always accessible on the shop floor. Unlike electronic thermometers, the Tempilstik requires no batteries, no calibration, and is immune to static electricity or electrical interference, making it robust enough for the harshest welding and fabrication environments. Each batch is laboratory tested to ensure consistency and traceability, providing peace of mind for quality assurance managers and inspectors alike.

FAQ

Simply stroke the workpiece with the stick before or during heating. When the mark turns from a chalky solid to a liquid smear, the rated temperature of 550°F has been reached.

The Tempilstik is accurate to within +/- 1% of its rated temperature (550°F), making it suitable for code-compliant work.

Tempilstiks are formulated to be safe for most metals. However, for critical applications, it is recommended to remove the mark before welding to prevent any potential contamination.

Yes, unlike infrared thermometers which struggle with emissivity on shiny surfaces, the Tempilstik relies on direct thermal conduction and works perfectly on polished metals.

No, the Tempilstik relies on the fixed melting point of its chemical composition, so it never requires calibration or batteries.

Absolutely. It is an excellent tool for ensuring the material stays within the required temperature range between passes.

The metal holder is designed to hold the stick securely. While the stick itself is consumable, the holder protects it during use and storage.

It meets the requirements of AWS D1.1, ASME Code Sec. I, III, and VIII, and ANSI/ASME Code B31.1 and B31.3.
