Product Overview
thin yellow rule
<empty>
The FCT-450 has been designed to have the highest possible accuracy for measuring high-efficiency solar cells. This is done using patented Voltage Modulation to neutralize the capacitive effects in I-V measurements.
<empty>
The Sinton analysis package includes standard cell test outputs. It is supplemented with the Suns-Voc analysis that precisely indicates the source of power loss with accurate shunt and series resistance measurements.
