The Extech 412300A is a Current Calibrator and Meter. Precision “source” for calibrating process devices and measuring DC process signals from 0 to 24mA with a super large LCD that displays readings in mA, as a percent of the 0 to 24mA range or as mV in voltage ranges. Additional features include Touch Keypad, five stored calibration values for fast calibrations, and 24VDC power to measure two-wire current loops. Complete with 9V Battery, calibration cable with spade lug terminals, carrying case, neck strap, and AC Power Adapter.

Supplied with six AA batteries, test leads or calibration cable, AC adapter and carrying case. NIST calibration Certificate optional.
