TR-Spy Mark II: Fully Automatic, Three Phase Transformer Turns Ratio Meter

The TR-Mark III R is the same instrument as the TR-Mark III but built in a 19” rack housing.

Therefore, it can be used very well in test labs or be assembled into complete measurement systems. The TR-Mark III R has a color LCD with a back light and touch screen, which increases handling and user comfort. Four USB interfaces make it easy to store measurements on external storage devices, transfer easily to a personal computer, and transfer or download nameplate data of the transformer to test.
