The Keithley 6517A 5 1/2 digit Electrometer / High Resistance Meter offers extreme accuracy and sensitivity specifications. It also offers a variety of features that simplify measuring high resistances and the resistivity of insulating materials. With reading rates of up to 125 readings/ second, the Keithley 6517A is also significantly faster than competitive electrometers, so it offers a quick, easy way to measure low-level currents.

The half-rack-sized Keithley 6517A has a special low current input amplifier with an input bias current of

The Keithley 6517A offers full autoranging over the full span of ranges on current, resistance, voltage, and charge measurements:

●Current measurements from 1fA to 20mA

●Voltage measurements from 10ìV to 200V

●Resistance measurements from 50Ù to 1016Ù

●Charge measurements from 10fC to 2ìC
