Keysight B2985A Electrometer/High Resistance Meter

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.

0.01fA minimum measurement resolution
10PΩ maximum resistance measurement with 1000V source
20,000 readings/s
< 20μV burden voltage
Time domain view to capture transients
Histogram view to perform quick data analysis
Other X-Y plots including I-V, I-t, R-t, Q-t, I-R
Easy-to-use auto navigation
Comes with high-performance Keysight triaxial cable (1.5m)


Keysight triax cable 1.5m, 16494A ( 888-2403 ) is supplied with the B2985A. Other lengths are available separately: 0.4m, 16494A-004 ( 888-2412 ); 0.8m, 16494A-003 ( 888-2403 ); 3m, 16494A-002 ( 888-2409 ); 4m, 16494A-005 ( 888-2415 ). Other Keysight B2900A accessories available separately include high resistance meter fixture adapter N1413A ( 888-2392 ) and high resistance measurement universal adapter N1414A ( 888-2396 ).
