Electrometer / High Resistance Meter (0.01fA), Battery Powered
The B2987B 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). In addition, battery operation eliminates AC line noise from your critical measurements. 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 to 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
