Precision Digital's PD660 and PD661 3-1/2 digit loop-powered meters are perfect for applications where a simple inexpensive display is required and no AC power is available. Even if the lighting is poor, the loop-powered backlighting option lets you see the display under any lighting condition. This option gets its power from the 4-20 mA input loop so there is no need for additional wiring and no batteries to ever change. The PD660 and PD661 are housed in rugged NEMA 4X and Explosion-proof enclosures so they can be mounted virtually anywhere. The only tools needed for calibration are a calibrated current source, a flat head screwdriver, and a Phillips head screwdriver.
