Keithley 6517B Electrometer / High Resistance Meter

The Keithley 6517B Electrometer / High Resistance Meter sets a new benchmark in accuracy and sensitivity for measuring high resistances and resistivity in insulating materials. Designed with advanced technology, this 5½-digit instrument streamlines the process of measuring low-level currents with its impressive reading rate of up to 425 readings per second. This enhancement allows professionals to conduct quick and reliable testing, making it an indispensable tool for researchers and engineers alike.

As a successor to the renowned Keithley 6517A, the 6517B retains software compatibility, enabling existing SCPI-based applications to run seamlessly. Notably, it brings significant improvements, including a robust internal battery-backed memory buffer that stores up to 50,000 readings. This feature empowers users to capture and log test results over extended periods, enhancing data management capabilities. The new model also boasts faster reading rates for both internal and external data storage, supporting up to 400 readings/second via the IEEE bus.
