The Practical Instruments Electronics (PIE) range of hand held calibrators cover all the areas that a workshop or technician would require to successfully calibrate or troubleshoot most instrumentation. There are both simulators and calibrators for RTD’s and Thermocouples. They not only offer a standard 4-20mA/Voltage calibrator, but also one with loop diagnostics which displays loop current, voltage, resistance, AC voltage and mode of operation simultaneously eliminating multiple DMM connections.<br>To complete the range there is a dual input 4-20mA Calibrator and a Frequency Calibrator. The complete range of high accuracy, user friendly instruments is listed in the following pages, with a brief outline on the features available. Full brochures are available on request.
