PIE Voltage Products

Voltage units from Practical Instrument Electronics (PIE) all feature the timesaving EZ-DialTM Knob and EZ-CheckTM Switch. Make fast adjustments with the EZ-Dial™ knob or test limits with the Dual Action EZ-Check™ switch. 

Many other calibrators require that you break the loop to calibrate voltage inputs. With the PIE 235 you simply clip the test leads across the voltage inputs in a live 4 to 20 mA loop without disconnecting any wires.

The Model 532 brings all the features you would expect from a loop calibrator plus troubleshooting tools! 

The Model 535 is a 4-20 milliamp calibrator, but also includes 10-50 milliamp process loops, with HIGH accuracy and repeatability designed in collaboration with Nuclear plants.
