PIE Voltage Calibrators


The Practical Instrument Electronics (PIE) Model 235 Process Voltage Calibrator sources and reads a variety of process DC voltage signals including dedicated ranges for 1 to 5 Volts. Unique is the ability to calibrate 1 to 5 volt recorders in 4 to 20 mA loop without disconnecting any wires.

The Model 532 and 535 are the industry's premier handheld Voltage (V) and Milliamp (mA) calibrators. These units have fuse-less protection, rugged design, long battery life, and HARTŪ compatibility. The 532 and 535 can source and read both millimaps and Voltage!
