Graphical Picoammeter/Electrometer that confidently measures down to 0.01 fA and up to 10 PΩ
The Keysight B2981A and B2983A Femto/Picoammeters and B2985A and B2985A Electrometers/High Resistance Meters not only offer best-in-class measurement performance, but also provide unprecedented features to maximize your measurement confidence. The Femto/Picoammeters and Electrometers both offer 0.01 fA (10-17A) minimum current resolution, which meets virtually all existing and future low-level current measurement needs.
Unique capabilities and features maximize confidence for sensitive measurements
The electrometers feature a 1,000 V voltage sourcing capability that supports up to 10 PΩ (1016 Ω) resistance measurements. The electrometers also work with Keysight's well-proven high resistance meter accessories. Both the Femto/Picoammeter and Electrometer have battery powered versions to eliminate AC power line noise. This available capability provides an unmatched level of noise reduction, enabling low-level measurements that were previously impossible.
