Glass Braid Insulated Type-K Thermocouple
Thermocouples are best used for measuring temperatures that can go
above 100 °C. This is a bare wires bead-probe which can measure air
or surface temperatures. This one uses a fiberglass braid so it can be
used in high temperature measurements such as heaters and ovens.
There's a small piece of heat shrink on the end to keep the fiberglass
from fraying. If you're using at >250°C temperatures, simply remove it
with a small blade.
 K type thermocouple with glass over-braiding
 Good up to 500 °C (900 °F)!
 Color-coded wires
 1 meter long (a little more than 3 feet)
 Best used with a thermocouple amplifier such as
the MAX31855, AD8495 or MAX31856
