The Keithley 6514 System Electrometer delivers a powerful combination of sensitivity, accuracy, and affordability for applications requiring low-level current, high-resistance, voltage, and charge measurements. With current sensitivity down to 10 fA and resistance measurement capability up to 200 TΩ (2×10^14 Ω), the 6514 is engineered for demanding yet cost-sensitive laboratory and system test environments.
It is widely used in materials research, device characterization, and quality assurance testing, where accurate picoamp and femtoamp current measurements are critical. Its compact form factor and IEEE-488 (GPIB) and RS-232 interfaces make it ideal for integration into automated test systems.
The 6514 shares much of the performance of higher-end Keithley electrometers but provides a more economical solution, making it a popular choice for labs needing reliable precision without the cost of a built-in high-voltage source.
