The Keysight B2987A Electrometer/High Resistance Meter delivers femtoampere-level current measurement and petaohm-range resistance characterization for advanced materials, nanotechnology, and sensor development. This bench instrument combines ultra-sensitive DC measurements with real-time graphical analysis on an integrated 4.3″ TFT display, eliminating the need for external computers during transient capture and statistical evaluation. Battery operation removes AC line noise interference, preserving measurement integrity at the lowest current ranges.
