The TC-100 Thermocouple Calibrator provides high accuracy source and measurement of ten common thermocouples, as well as mV. The TC-100’s accuracy of ±0.3°C for Type J T/Cs includes all errors, at resolutions of ±0.01°C or °F in measure mode and ±0.1°C or °F in source mode. Features including MIN/MAX re-call in measure mode, three setpoints per thermocouple range, a large knob for decade control of the output in source mode, and the ability to accept bare T/C wires in addition to mini-plug inputs, makes the TC-100 an accurate, easy-to-use instrument for all your thermocouple calibration needs.
