Keysight B2985A electrometer/high resistance meter is the world’s only graphical electrometer that allows users to confidently measure small currents with 0.01fA resolution and large resistances of up to 10PΩ. It has a 4.3 inch colour LCD with a graphical user interface that provides trend chart and histogram data in addition to numeric information. These front-panel capabilities enable users to capture transient behaviour and to perform quick statistical analyses without a PC.
