Transformer winding Resistance Testers

Fully Automatic TRT-27 Series

Model : TRT-27-10 TRT-27-20 TRT-27-40

Description: UDEY TRT-27 is a new generation, digital resistance meter using 4 terminal measurement technique. Built in printer for printing results. The entire test is done quickly. TRT-27 generates constant current, powers up the test current, takes the readings, and displays the results on the LCD screen. The TRT-27 is encased in an aluminum alloy cabinet.
