PRT-73 Ratio Transformer

Brand: Tegam

The PRT-73 Automated Precision Ratio Transformer meets or exceeds all of the requirements for a calibration standard in precision measurement applications. 

It is easily integrated into systems for either automated or manual calibration of ratio dividers, transformer standards, synchro/resolver standards, transformers, calibrators, and voltmeters. 

The PRT-73 is fully programmable via a standard IEEE-488 interface increasing calibration throughput reducing operator intervention.
