[PIE] PIE 334 4-20mA Loop Calibrator
Precision milliamp loop calibrator
제품특징
The Piecal 334 is functionally equivalent to similar calibrators with four digit displays, knobs and switches. Improvements over 334s from other manufacturers include better long term stability, accuracy, reliability and ruggedness plus improved battery life.
The Piecal 334 gives you advantages of an updated design while maintaining the familiar, time proven ease of use of similar calibrators. The Piecal 334 is the perfect replacement for your worn out milliamp calibrators.
