Temperature indicator stick blue | 500 °C

Temperature Indicating Crayon, Blue | 500 °C

Part number: 311065

Product Description

The Wieländer+Schill temperature indicator crayons are heat-sensing devices with precisely calibrated melting points. These indicators are ideally suited for reliably determining surface temperatures in industrial and body repair applications. The blue version of the product is specifically designed to accurately indicate when the surface has reached a temperature of 500 °C.

The marking material melts (flows out) when the specified nominal temperature is reached, visually and unambiguously indicating the critical temperature point. This method is extremely useful for monitoring processes where precise adherence to heat treatment is essential for quality and safety.

Key Features and Advantages

• Precise Temperature Indication: The melting point of the crayon is strictly calibrated, thus providing reliable feedback on the surface temperature.

• Easy Interpretation: The mark flows out unequivocally when the critical temperature is reached, providing immediate visual confirmation.

• Wide Range of Applications: Ideal for welding, metal processing, and heat treatment processes.

• Application Flexibility: Marking of the workpiece can be performed either before or during the heating process.

• Optimized for Smooth Surfaces: Ensures the best result on smooth, clean surfaces.

Application Areas

This 500 °C temperature indicator crayon is an essential tool in the following areas:

• Welding and Metal Processing: For pre-weld and post-weld temperature monitoring.

• Preheating: Ensures the workpiece reaches the minimum temperature required for welding.

• Intermediate Storage: Monitoring temperature stability between different phases.

• Heat Treatment after Welding: Checking for maintenance of the required post-treatment temperature for stress relief.

• 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.

Technical Data

The product specifications ensure reliable and repeatable measurement even in the most demanding industrial environments.

Usage Guide

The use of the temperature-indicating pencil is simple, but requires a precise result:

1. Marking: Apply a line or dot to the surface of the workpiece whose temperature you wish to measure. Perform the marking before or during the heating process.

2. Heating: Begin warming up the workpiece according to the desired procedure.

3. Inspection: Observe the marking. When the surface reaches exactly 500 °C, the mark left by the crayon will unequivocally melt and flow out.

4. Evaluation: The melted mark confirms that the surface has reached the target temperature. If the mark has not melted, the temperature has not yet reached 500 °C.
