The SS3250/3252/3302 transformer test instrument is a precision test system, designed for transformer production line or incoming/outgoing inspection in quality control process, with high stability and high reliability. With the enhanced capability in turn ratio measurement, they can solve the measuring problems of low coupling coefficient, transformer's turn ratio and turn number with more precise measurement. In addition to transformer scanning test function, the 3302/3252 have LCR Meter function. Operator-friendly and value-added, they can help you reduce production cost greatly.
