Adafruit Thermocouple Type-K Glass Braid Insulated - 5m

Thermocouples excel in environments where temperatures exceed 100°C, making them ideal for high-temperature applications. This particular model features a bare-wire bead-probe suitable for measuring air or surface temperatures, providing versatile solutions across various settings.

Unlike cheaper options with vinyl coverings that risk melting around 200°C, this thermocouple uses a durable fiberglass braid, allowing it to withstand high temperatures commonly found in heaters and ovens. Its K type specification with glass over-braiding supports temperatures up to 500°C (900 °F) for reliable performance in demanding conditions.

The design includes color-coded wires extending 5 meters, ensuring ease of installation and integration with systems. For optimal performance, especially beyond 250°C, the small heat shrink at the end can be removed to prevent fraying.

This thermocouple pairs effectively with amplifiers such as the MAX31855, AD8495, or MAX31856, enhancing reading precision. Comprehensive support is available, featuring tutorials that include CircuitPython and Arduino libraries alongside example code to facilitate seamless implementation.
