Quick Disconnect Style	Transition Junction Style
	Probes of 1 mm diameter and larger supplied with transition joint moulded to probe. Smaller sizes supplied with metal joint.

The OMEGA subminiature thermocouple assemblies are designed for use in locations where small probe diameters are required. These probes are available with grounded, ungrounded or exposed junctions, with 304 SS, 321 SS or Inconel sheaths. Quick disconnect subminiature connector (type SMP) or subminiature transition junction cold end terminations are standard. Terminations are colour-coded to the thermocouple type and are stamped with the thermocouple code letter.
