Toroidal Coil Precision Tester.
The number of turns tester developed by Grewin is a practical toroidal coil number of turns measuring instrument, which is mainly suitable for the measurement of the number of turns of various toroidal coils. Such as inductance coils, transformer coils, toroidal transformer coils, etc. Due to the adoption of new digital circuit technology, the instrument has high test accuracy. After calibration of the sample coil, it can have a resolution of up to 0.1%, which can meet the quality assurance of the production line and the high-precision measurement requirements of the laboratory.
