Keithley 6517B
Electrometer/Hi Resistance Mtr
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 10aA (10x10-18A,) charge levels down to 1fC, and the highest resistance measurements available up to 1018O. The 6517B also is capable of measuring the largest voltage range - up to 200V - with an input impedance exceeding 200TO.
