Original Press Release:

New Low Cost Portable 4-20mA Calibrator

This low cost, portable calibrator model 420 was designed for calibration/test of DPMs, PLCs, transmitters, sensors or any other device requiring a 4-20mA current loop signal. The 4x2.5x4" housing comes with a belt clip for ease of operation. Powered by a 9V transistor-type battery, this unit operates down to 6V and can drive up to 300 Ohm loads or sustain up to 7V burden of the load. The calibrator features a dual full scale range of 19.99 and 25.0mA, a 10-turn potentiometer for precise. The 420 3 ½ digit built-in display will only turn on if the "loop" is closed (connected) useful for troubleshooting loops.
