Precision Digital PD675 and PD677 4-1/2 Digit Loop-Powered Process Meters

Tired of dummy zeroes or multipliers? Want to know what your real measured variable is? The Precision Digital PD675 and PD677 are capable of displaying numbers up to 19,999 with 1 count resolution. (So, they display numbers like 7124, 15697 or 124.78 as whole numbers.) Calibration is easy, and the only tools you need are a calibrated current source, a flat head screwdriver, and a Phillips head screwdriver.

The NEMA 4X PD675, with its impact-resistant polycarbonate body, is FM approved and CSA certified non-incendive for Class I, II, and II indoor and outdoor locations. The cast aluminum-enclosed PD677 is suitable for explosion-proof and dust-ignition-proof environments, and is available with FM approval and CSA certification for Class I, Class II, and Class III hazardous locations.
