6487 Picoammeter/Voltage Source

The 5 1/2 digit Model 6487 Picoammeter/Voltage Source improves on the measurement capability of Model 6485, and adds a high resolution 500 V source.

  In our effort to bring our customers the highest level of precision measurement capabilities, Fluke Calibration is proud to offer these precision metrology grade products from Keithley Instruments. Renowned as a leader in low-level precision electrical measurements, these selected Keithley products present an opportunity to help you further reduce uncertainties in your lab. The 5 1/2 digit Model 6487 Picoammeter/Voltage Source improves on the measurement capability of the award-winning Model 6485, and adds a high resolution 500 V source. It provides higher accuracy and faster rise times than the 6485, as well as a damping function for use with capacitive devices. With eight current measurement ranges and high speed autoranging, this cost-effective instrument can measure currents from 20 fA to 20 mA, take measurements at speeds up to 1000 readings per second, and source voltage from 200 μV to 505 V.
