The Practical Instrument Electronics Model 521 Thermocouple Simulator simulates a standard thermocouple curve over the entire industrial temperature range. Choose between eight standard T/C types or millivolts.

The Model 521 sources precise temperatures for inputs to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. The Model 521 provides a miniature T/C connector and is internally cold-junction compensated for changes in ambient temperature. The PIE Model 521 offers the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced thermocouple calibrators.

The EZ-Check function allows the user to store three output temperatures for real convenience. This will save time for repetitive calibrations by instantly recalling the three stored temperature values. Three output settings can be stored, and all settings are saved, even with the power off.
