Keithley 6487/J Picoammeter/Voltage Source, 100Vac Line Voltage

The Keithley 6487/J Picoammeter/Voltage Source is designed for researchers and engineers who require ultra-low current measurements alongside a reliable high-voltage source. Combining picoamp sensitivity down to 10 fA with a programmable 500V source, this instrument provides a cost-effective and space-saving alternative to separate devices.

With a current measurement range of 20 fA to 20 mA, high accuracy of ±0.3%, and fast digitizing capability of up to 1000 readings/second, it is ideal for applications such as I-V characterization, leakage current testing, insulation resistance, and detector evaluation.

This “/J” variant is configured for 100Vac line voltage, ensuring compatibility with regional power standards, while offering the same trusted performance as the global 6487 family.
