Femto / Picoammeter (0.01fA)

The B2981B Femto/Picoammeter is the world’s only graphical picoammeter that allows you to confidently measure small currents with 0.01fA (0.01 x 10⁻¹⁵ A) resolution. It possesses a 4.3” color LCD with a graphical user interface that provides trend charts 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 the noise levels of different cabling and fixturing arrangements to help isolate external noise sources.

Several versions available
