A Type-K thermocouple with fiberglass braid insulation, rated to 500°C — far beyond the ~200°C limit of standard vinyl-insulated thermocouples. The bare bead probe design is suited to measuring both air and surface temperatures in high-heat environments such as ovens, kilns, heaters, and industrial processes.
Requires a thermocouple amplifier (such as the MAX31855, AD8495, or MAX31856) to interface with a microcontroller.
Specifications
- Type – K
- Insulation – Glass fibre braid
- Maximum Temperature – 500°C (900°F)
- Length – 1 metre
- Probe Style – Bare bead (air and surface measurement)
- Wires – Colour-coded
Ideal For
- Oven, kiln, and heater temperature monitoring
- High-temperature industrial and maker applications
- Any application exceeding standard vinyl thermocouple limits

Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- Thermocouple
- A temperature sensor made from two different metals that produces a very small voltage depending on temperature. Because the signal is tiny, it usually needs careful amplification and accurate measurement hardware.
