Express post delivery (2-5 business days)

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
Note: A small piece of heat shrink protects the fiberglass end from fraying. Remove it with a blade if using above 250°C. Some units may have red and yellow wires colour-coded in reverse — if temperature readings decrease when you heat the probe, flip the two wires.
