Keysight B2985C Electrometer/High Resistance Meter

Overview

The Keysight B2985C is a high-performance electrometer and resistance meter providing exceptional measurement capabilities for research and material characterization. With a minimum current resolution of 0.01 fA (10⁻¹⁷ A) and resistance measurement up to 10 PΩ (10¹⁵ Ω), it addresses the most demanding low-level measurement applications. The 4.3-inch color LCD graphical interface delivers real-time trend visualization, histograms, and advanced data analysis without requiring external software.
