This 5m Type-K thermocouple is a bare-wire bead probe designed for measuring air or surface temperature in applications where standard plastic-insulated probes may fail. It uses a glass over-braided insulation that is better suited to elevated temperatures found around heaters, hot plates, furnaces, and ovens.
Unlike low-cost thermocouples with vinyl insulation that can soften or melt around 200°C, this version is rated for use up to 500°C. The color-coded leads make polarity identification easier when wiring it to a compatible thermocouple amplifier or interface board.
Because this is a bead-style bare-wire sensor, it is a practical choice for fast-response temperature sensing in air streams, on surfaces, or in experimental thermal setups. It is best paired with a thermocouple amplifier such as the MAX31855, AD8495, MAX31856, or MCP9600 for easy use with microcontrollers and SBCs.
Technical details for the Type-K Thermocouple with Glass Braid Insulation - 5m.

This thermocouple is intended for use with a suitable thermocouple amplifier or converter. For K-type-only analog interfacing, the AD8495 is a simple option. For digital interfacing over I2C and support for multiple thermocouple types, the MCP9600 is a flexible choice.
Important: there is a small piece of heat shrink near the end to keep the fiberglass braid from fraying. If you plan to use the probe at temperatures above 250°C, remove that heat shrink carefully with a small blade before use.
Typical compatible amplifier options mentioned by the supplier include MAX31855, AD8495, MAX31856, and MCP9600.
This is a Type-K thermocouple with glass braid insulation. It is a bare-wire bead probe designed for measuring air or surface temperatures.
According to the supplier brief, it is good up to 500°C (900°F). It is intended for higher-temperature measurements such as heaters and ovens, where common vinyl-insulated probes may not be suitable.
The fiberglass braid is used so the cable can handle higher temperatures than typical vinyl-covered thermocouples, which may melt around 200°C. This makes it better suited for hotter environments.
The thermocouple is 5 meters long and about 1.6mm thick. Its listed weight is 13.5g.
The supplier recommends using it with thermocouple amplifiers such as the MAX31855, AD8495, or MAX31856. It is also compatible with K-type capable interfaces like the MCP9600 when configured for Type-K input.
Yes. There is a small piece of heat shrink at the end to prevent the fiberglass from fraying, and the supplier notes that if you are using it above 250°C, you should remove that heat shrink with a small blade.
