The 712B RTD and 714B thermocouple temperature calibrators test process temperature instrumentation. 712B measures and simulates 13 resistance temperature detector (RTDs) types and resistance. 714B measures and simulates 17 thermocouple types, as well as millivolts, to verify process sensors by comparison of measured versus reported temperatures. They measure 4-20 mA signals with 0.001-mA resolution.
