Type J thermocouple temperature probe

The 1118 Series, manufactured by Marsh Bellodram® is an engine thermocouple, a stainless steel over-wrap material that can hold off high temperature glass braid insulation while providing high conductivity, plus, preventing vibration of wires and an oxidation reduction. It comes with two standard calibrations, such as Iron/Constantan (Type J) and Chromel/Alumel (Type K). They are designed to satisfy different configurations in assuring durability of a thermocouples in any worst situations it face.
