TR-Mark III R 250V

TR-Mark III R 250V: Fully Automatic, Three Phase Transformer Turns Ratio Meter

The TR-Mark III R 250V turns ratio is the same instrument as the TR-Mark III 250V, but built into 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 250V offers new features and increased accuracy to make it a perfect system. A color LCD with a back light and a touch screen 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.
