Keysight Agilent B2985B Electrometer High Resistance Meter, 0.01fA
The B2985B Electrometer/High Resistance Meter is the world's only graphical electrometer that allows you to confidently measure small currents with 0.01 fA (0.01 x 10-15 A) resolution and large resistances of up to 10 PΩ (10 x 1015 Ω). It features a 4.3" color LCD with a graphical user interface that provides trend chart and histogram data in addition to numeric information. These front-panel capabilities enable you to capture transient behavior and perform quick statistical analyses without a PC. The available Setup Integrity Checker software option allows you to compare noise levels of different cabling and fixturing arrangements to help isolate external noise sources.
