New, never used ACTION INSTRUMENTS Model T808 4-20MA SOURCE SIGNAL INJECTOR.

The Action Model T808 4-20mA Calibrator is a self-contained, high precision instrument whichis ideal for calibrating two-wire transmitters such as the Action T702 or T703 Voltage or Current Input Wide-Ranging Transpak.   

The dual-function T808 combibes a two-wire calibrator and a self-contained current source in the same pocket-sized instrument.  The light-weight T808 is ideal for firld, control room, or shop use.  The unit's small size is made possible by its up-to-date design, which also provides a precision reference, ultra-stable amplifier, and high-gain-power Darlington output.

The two-wire calibration mode utilizes external loop power to provide a precisely adjustable 4-20mA signal.  Loop power my vary from 6 to 45Vdc.  In the source mode only, built in batteries are used to provide a continuously adjustable 4-20mA into any load from 0-800 ohms.

Comes with storage bag.
