Solar Cell I-V Tester

Overview

The new VS-6820 provides Cell manufactories & laboratories a new experience in testing and measuring of photovoltaic cells. It provides complete coverage of testing parameters and measurement requirements from most international standards. Its test methods, procedure & equipments are compliant with International standard IEC 60904. Calibration of reference cell is performed at ISE Fraunhofer Germany, and is traceable to PTB.
