Keysight B2985C Electrometer / High Resistance Meter

Keysight B2985C Electrometer / High Resistance Meter – Ultra-Precise Measurement Down to 0.01 fA and Up to 10 PΩ

The Keysight B2985C Electrometer / High Resistance Meter is a high-precision measurement instrument designed for detecting ultra-low currents and extremely high resistances with unmatched accuracy. It provides 0.01 fA (0.01 × 10⁻¹⁵ A) resolution and measures resistances up to 10 PΩ (10 × 10¹⁵ Ω) using its integrated 1000 V voltage source.

Equipped with a 4.3-inch color LCD display, the B2985C allows real-time graphical visualization of trend charts, histograms, and numeric data directly on the instrument. This eliminates the need for a PC during analysis, enabling engineers to observe signal stability, noise levels, and transient behavior immediately.

The Setup Integrity Checker software enhances diagnostic capability by identifying external noise sources through cable and fixture comparison. This ensures precise and stable measurements, even in challenging environments.

With its combination of precision, speed, and usability, the Keysight B2985C is an essential tool for semiconductor testing, material research, and insulation characterization applications that demand extreme sensitivity and consistency.
