# Temperature Indicator Pencil, Green | 204 \u00b0C<\/p>\n
**Part Number:** 311063<\/p>\n
This product is a precision temperature indicator pencil designed to reliably signal the achievement of surface temperature during industrial applications. The temperature indicators are marking devices with a calibrated melting point, essential for the accurate monitoring of heat treatment processes.<\/p>\n
## Product Description and Operating Principle<\/p>\n
Temperature indicator pencils contain a marking material with a specific, calibrated melting point. When the marked surface reaches the pencil's nominal temperature, the mark clearly melts (flows away), visually indicating that the critical temperature has been reached.<\/p>\n
This green temperature indicator pencil is specifically designed for the precise detection of the **204 \u00b0C** temperature.<\/p>\n
### Key Features and Benefits<\/p>\n
* **Precise Temperature Indication:** The melting of the indicator reliably signals the achievement of the set temperature.
\n* **High Accuracy:** Compared to the nominal temperature, the measurement accuracy is only **+\/- 1%** deviation.
\n* **Simple Application:** The workpiece must be marked before or during heating. The melting of the indicator provides immediate visual feedback.
\n* **Ideal Surfaces:** Suitable for determining the temperature of smooth surfaces.<\/p>\n
## Application Areas<\/p>\n
This 204 \u00b0C temperature indicator pencil is an ideal choice for monitoring numerous critical industrial processes, especially in cases where maintaining the temperature within a strict range is essential for quality assurance and safety.<\/p>\n
The application areas of the marking pencil include:<\/p>\n
* **Welding and Metal Processing:** Temperature monitoring before or after welding seams.
\n* **Preheating:** Verification of the optimal preheating temperature for metal parts before welding.
\n* **Intermediate Storage:** Checking temperature stability between heat treatment phases.
\n* **Heat treatment after welding:** Monitoring the temperature profile of stress-relieving or subsequent hardening heat treatments.
\n* **Soft Annealing:** Execution of the metal annealing process at the appropriate temperature.
\n* **Stress relief annealing:** Confirmation of the required heat treatment temperature for eliminating internal stresses.<\/p>\n

## Further Temperature Indicator Options<\/p>\n
In addition to the 204 \u00b0C indicator, the product family covers other temperature ranges, ensuring comprehensive temperature monitoring:<\/p>\n
| Part Number | Color | Nominal Temperature |
\n| :— | :— | :— |
\n| 311062 | Red | 100 \u00b0C |
\n| 311063 | Green | 204 \u00b0C |
\n| 311064 | Yellow | 400 \u00b0C |
\n| 311065 | Blue | 500 \u00b0C |<\/p>\n
These accessory products (100 \u00b0C, 400 \u00b0C, and 500 \u00b0C) operate on the same principles and are equally suitable for temperature control in industrial and welding applications on smooth surfaces.<\/p>\n
