Meters used with thermocouples were d'Arsonval movements, with a low resistance moving coil, and a fine hairspring, so that sensitivity was typically one or two milliAmps FSD. They were commonly used with couples to measure temperature remotely, or to measure RF current in an antenna feed line. This meter was used with a temperature measuring thermocouple.
