This detailed product description showcases the temperature indicator crayon with a calibrated melting point, offered by Wieländer+Schill, which is an essential tool for precise surface temperature monitoring in various industrial applications, especially in metal processing and welding.
The red temperature indicator crayon with a 100 °C melting point is a special marking tool with a calibrated melting point. The mark visually changes unambiguously (melts, flows out) when the surface reaches the exactly defined nominal temperature. This reliable method ensures that critical heat treatment processes, such as preheating or stress relief after welding, occur exactly at the desired temperature.
The product is an ideal choice for any professional who requires quick, simple, and visually verifiable temperature feedback on the surface of workpieces.
Accurate Temperature Indication: The pencil's melting point is precisely calibrated to 100 °C, providing reliable feedback when the critical temperature is reached.
Outstanding Accuracy: It operates with an accuracy of only $pm 1%$ deviation compared to the nominal temperature, guaranteeing strict adherence to processes.
Visual Reliability: The mark melts and flows out clearly on the surface when the set temperature is reached, providing immediate visual confirmation.
Wide Range of Applications: Can be used for numerous temperature-sensitive processes, especially during welding and metalworking operations.
Simple Operation: The workpiece surface should be marked before or during heating. This method is best suited for smooth surfaces.
This temperature indicator crayon is an indispensable tool in the following areas:
Welding and Metal Processing: For temperature monitoring before or after welding seams.
Preheating: Ensures that metal parts reach the minimum temperature required for welding or machining.
Intermediate Storage: Temperature stability monitoring during storage phases.
Heat Treatment after Welding: Checking the maintenance of critical post-treatment temperatures.
Annealing (Soft Annealing): Confirmation of the optimal temperature for the annealing process.
Stress Relief Annealing: Monitoring compliance with the required temperature profile necessary to eliminate internal stresses.
The product specifications ensure reliable and long-lasting performance even in the most demanding workshop environments.

The use of the temperature indicating crayon is very simple, but for the best results, follow the steps below:
Marking: Use the pencil to mark a line or dot on the surface of the workpiece whose temperature you wish to check. The mark should ideally be made immediately before or during the heating process.
Heating: Begin heating the workpiece according to the desired procedure.
Inspection: Observe the mark. As soon as the surface temperature reaches 100 °C, the mark left by the pencil will visually change (melt and flow out).
Interpretation: The melting of the mark clearly indicates that the surface has reached the 100 °C threshold.
This method is particularly useful in situations where using a digital thermometer is difficult or impossible, or where quick, immediate visual confirmation of the correct process run is required.
In addition to the 100 °C indicator, Wieländer+Schill offers a wide range of options for other temperature ranges, ensuring there is a suitable tool for every heat treatment requirement:
Temperature Indicator Pencil, Blue | 500 °C (Part No.: 311065): For higher temperature monitoring.
Temperature Indicating Crayon, Yellow | 400 °C (Part Number: 311064): For medium to high temperature ranges.
Temperature Indicator Pencil, Green | 204 °C (Part No.: 311063): For medium temperature monitoring.
All of these accessories utilize the same reliable $pm 1%$ accuracy technology, thus covering the entire heat treatment process scale.
