Product Details

brief introduction

Model GKT3252/3302 transformer tester is a high-precision measuring instrument with high stability and reliability, which is provided to the production line or quality control of the transformer factory for incoming and outgoing inspection. Technically, the ability to enhance the coil ratio can solve the problems of low coupling coefficient, transformer coil ratio, and coil number measurement, so as to make the measurement results more accurate. In addition to the test function of transformer scanning, the 3252/3302 also has the LCR measurement function, which is not only easy to operate, but also can reduce the cost of production equipment.
