The standard Nanmac High Temperature Probe consists of an ungrounded thermal junction within a closed end sheath. It also includes a set of standard matching plug and jack connectors. The male connector attached and the female connector (not shown) are furnished with a cable clamp. Maximum service temperature of the connector is 450 degrees Fahrenheit.

The standard High Temperature Probe is available with a four inch support tube attached to the connector end. The purpose of the support tube is to eliminate any damage to the refractory sheath which may be caused by the mounting bushing. The support tube is an 1/8 inch larger in diameter than that of the thermocouple sheath. If a support tube is desired, add the suffix (ST) to the part number.
