Keithley 6517B Electrometer/High Resistance Meter

The Keithley 6517B Electrometer/High Resistance Meter is a high-performance benchtop instrument designed for ultra-low current, high resistance, voltage, and charge measurements in demanding laboratory, research, and production environments. Widely recognized as a standard for sensitive electrical testing, the 6517B delivers measurement capability down to 10 aA, charge sensitivity down to 1 fC, and resistance measurements up to 10¹? ohms, making it ideal for materials research, insulation testing, semiconductor characterization, nanotechnology, and precision electronic component evaluation.

Built for users who need exceptional accuracy and repeatability, the Keithley 6517B combines advanced low-level measurement performance with practical bench usability. It offers a built-in ±1000 V voltage source, greater than 200 T? input impedance for voltage measurements, and fast reading speeds of up to 425 readings per second, helping engineers and technicians perform reliable high-resistance and insulation measurements with confidence. These capabilities make the 6517B especially valuable for testing highly resistive materials, leakage current, insulation resistance, and other low-level electrical parameters that standard meters cannot measure accurately.

The Keithley 6517B is also designed to simplify difficult measurement tasks. Features such as its voltage reversal method for high resistance measurements and compatibility with optional scanner cards and resistivity accessories help streamline test setups for more efficient operation. Whether you are evaluating dielectric materials, performing picoamp current measurements, or conducting advanced insulation resistance testing, the 6517B offers the precision, flexibility, and proven reliability expected from Keithley’s low-level measurement instruments.
