The Keysight B2987B is a battery-operated electrometer and high resistance meter engineered for precision measurement of extremely low currents and ultra-high resistances. With minimum current resolution down to 0.01 fA and maximum resistance measurement capability of 10 PΩ, this instrument delivers sensitivity far beyond conventional digital multimeters. Battery operation eliminates AC power line interference, enabling noise-free measurements critical for low-current characterization and charge analysis.
