Part number: 311064
Wieländer+Schill temperature indicator pencils are tools with precisely calibrated melting points, essential for the reliable monitoring of surface temperature during various industrial processes. This yellow marking pencil is specifically for the 400 °Cdetermination of the - degree temperature point.
These temperature indicators are crucial aids in welding and metalworking technologies, as well as heat treatment processes. The marking becomes clearly visible when the surface reaches the pencil's calibrated melting point: the mark melts (flows out), visually confirming that the desired temperature has been reached.
Accurate Temperature Monitoring: The melting point of the marking material is calibrated precisely to 400 °C.
Outstanding Accuracy: compared to the nominal temperature, only a +/- 1 %deviation in measurement accuracy. This strict tolerance ensures process quality assurance.
Visual Feedback: The melting of the mark provides an immediate, clear, and easily detectable visual signal that the critical temperature has been reached.
Application Versatility: Ideal for numerous heat treatment and metalworking operations where strict control of surface temperature is essential.
Simple Operation: The workpiece surface must be marked with the pencil before or during heating. The method is most effective on smooth surfaces.
This 400 °C temperature indicator pencil is ideal for determining the surface temperature in the following areas:
Welding and Metal Processing: Checking temperature requirements before or after welding seams.
Preheating: Ensuring the material reaches the minimum required temperature for welding or machining.
Intermediate Storage: Checking that materials are held at the appropriate temperature between manufacturing phases.
Heat Treatment after Welding: Precise adherence to critical post-treatment temperatures to reduce stress and maintain material quality.
Annealing (Soft Annealing): Confirmation of the optimal temperature for the annealing process.
Stress Relief Annealing: Checking the temperature range required to eliminate internal stresses.

The use of the temperature indicating crayon is very simple, but for the best results, follow the steps below:
Preparation: Ensure that the surface to be processed is clean and smooth. Marking only works reliably on smooth surfaces.
Marking: Apply the yellow mark to the area of the workpiece where you want to check the temperature. Apply the mark before or during the heating process.
Heating: Begin warming up the workpiece according to the desired procedure.
Indication: Observe the applied mark. When the surface temperature reaches 400 °C, the mark will visually melt and run. This signal confirms that the critical temperature has reached the target value.
This method offers a fast, cost-effective, and reliable alternative to electronic thermometers when quick, local temperature monitoring is needed during the manufacturing process.
In addition to the 400 °C indicator, the product family covers other temperature ranges, ensuring full-spectrum temperature monitoring:
Temperature Indicator Pencil, Green | 204 °C (Part No.: 311063): Ideal for checking lower temperature points, such as 204 °C.
Temperature Indicator Pencil, Blue | 500 °C (Part No.: 311065): For higher temperature applications, indicating the achievement of 500 °C.
Temperature Indicator Pencil, Red | 100 °C (Part No.: 311062): For low-temperature processes, for checking 100 °C.
These complementary products allow users to precisely track the temperature at every phase of the entire heat treatment cycle.
