The Extech 422123 precision multifunction calibrator provides an accurate calibration source for thermocouple, mA, mV, V, and frequency devices. With the Extech 422123 precision multifunction calibrator, the user can set output steps from 1% up to 100%, view the data on a large 5-digit LCD display, and hear a beep if the load is open with Current (mA) or the output is shorted with Voltage output.

The Extech 422123 precision multifunction calibrator can accurately source:

DV voltages from 0 to 10 volts with a resolution of 1mV;
DC currents from 0 to 24mA;
Types K, J and T thermocouples.

Additionally the Extech 422123 precision multifunction calibrator can measure DV voltages from 0 to 20 volts and DC current from 0 to 50mA. Other features of the Extech 422123 precision multifunction calibrator include high resolution, the ability to drive current loads up to 1000Ω, automatic ramp output, and an external battery pack for extended field applications.

The Extech 422123 precision multifunction calibrator comes complete with 9V battery, external battery pack (six AA batteries), case, alligator clips, and Type K and Type J test cables.
