Product Details

Introduction

Model GKT3252/3302 transformer tester is a high-stability, high-reliability precision measuring instrument, which is provided to the production line or quality control of transformer factory for import and export inspection. Technically, the ability to enhance the turns ratio can be used to solve the problems of low coupling coefficient, transformer turns ratio, turns measurement, etc., so that the measurement results can be more accurately determined. In addition to providing you with the test function of transformer scanning, 3252/3302 also has the LCR measurement function, which is not only easy to operate, but also reduces the cost of production equipment.
