The Keithley 6517B Electrometer/High Resistance Meter is the worldwide research laboratory standard for sensitive measurements. With over 60 years of low level measurement expertise, Keithley electrometers provide reliable measurements of current levels down to 10 aA (10×10–18 A), charge levels down to 1 fC, and the highest resistance measurements available up to 1018 Ω. The 6517B is also capable of measuring the largest voltage range—up to 200 V—with an input impedance exceeding 200 TΩ. All this performance is built into an instrument that operates as simply as a digital multimeter.

Exceptional Performance Specifications

The 6517B has incorporated Keithley’s decades of expertise in low level measurement technology into an innovative, low current input amplifier with an input bias current of <3 fA, just 0.75 fA p-p noise, and <20 μV burden voltage on the lowest current ranges. The voltage circuit input impedance is greater than 200 TΩ for nearideal circuit loading. These specifications ensure the accuracy and sensitivity needed for accurate low current and high impedance voltage, resistance, and charge measurements in areas of research such as physics, optics, nanotechnology, and materials science. A built in ±1 kV voltage source with sweep capability simplifies performing leakage, breakdown, and resistance testing, as well as volume (Ω-cm) and surface resistivity (Ω/square) measurements on insulating materials.
