 YH7021 Thermocouple Calibrator is a precise source and measurement tool for calibrating thermocouple instruments through a thermocouple mini jack. The calibrator can be indicated in units of °C, °F , or mV.

• Measure temperature from TC output

• Simulate TC output

• Operable with eight types of thermocouples

• Calibrate linear TC transmitter with mV source function

• Selectable °F or °C
