WebFeb 14, 2024 · 1) Exposed junction thermocouples are when the sensing wires are joined together out beyond the end of the probe sheath. Exposed junction thermocouples have the fastest response time to temperature changes, but because the sensing junction is exposed, it is more vulnerable to breakage. These probes are usually used to measure gases.
