The NC series solidpak thermocouples are the high performance thermocouples that feature high sensitivity, solidity, and durability required in a general industrial sensor. The gap between a protective tube and a thermocouple wire is densely filled with magnesium oxide. The thick protective tube provides excellent response along with vibration resistance and impact resistance. In addition, it allows the thermocouple to withstand long-term continuous operation in hot and unfavorable environment.
