# Temperature Indicator Crayon, Blue | 500 \u00b0C<\/p>\n
**Part Number:** 311065<\/p>\n
## Product Description<\/p>\n
The Wiel\u00e4nder+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 \u00b0C.<\/p>\n
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.<\/p>\n
### Key Features and Benefits<\/p>\n
* **Precise Temperature Indication:** The crayon's melting point is strictly calibrated, providing reliable feedback on the surface temperature.
\n* **Easy Interpretation:** The mark unambiguously flows out when the critical temperature is reached, providing immediate visual confirmation.
\n* **Wide Range of Applications:** Ideal for welding, metal processing, and heat treatment processes.
\n* **Application Flexibility:** Marking of the workpiece can be done before or during heating.
\n* **Optimized for Smooth Surfaces:** Ensures best results on smooth, clean surfaces.<\/p>\n
### Application Areas<\/p>\n
This 500 \u00b0C temperature indicator crayon is an essential tool in the following areas:<\/p>\n
* **Welding and Metal Processing:** For temperature checking before and after welding seams.
\n* **Preheating:** Ensures the workpiece reaches the minimum temperature required for welding.
\n* **Intermediate Storage:** Checking temperature stability between different phases.
\n* **Heat Treatment after Welding:** Checking the maintenance of the required post-weld heat treatment temperature to reduce residual stress.
\n* **Soft Annealing:** Confirmation of the optimal temperature for the soft annealing process.
\n* **Stress Relief Annealing:** Checking adherence to the temperature profile necessary to eliminate internal stresses.<\/p>\n
## Technical Data<\/p>\n

## User Guide<\/p>\n
The use of the temperature-indicating pencil is simple, but requires a precise result:<\/p>\n
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.
\n2. **Heating:** Begin heating the workpiece according to the desired procedure.
\n3. **Checking:** Observe the marking. When the surface reaches exactly 500 °C, the mark left by the pencil will clearly melt and flow off.
\n4. **Evaluation:** The melted marking confirms that the surface has reached the target temperature. If the marking has not melted, the temperature has not yet reached 500 °C.<\/p>\n
