The 520B single type T/C simulator simulates a dedicated standard thermocouple curve over the entire industrial temperature range. The 520B provides precise temperature for inputs to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. 520B is cold-junction compensated for changes in ambient temperature. And offers the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced thermocouple calibrators

The low price offered by of 520B is "easy as PIE" to use thermocouple source for checkout and calibration of all thermocouple instruments in the field, shop or control room.
