Keithley 6485

The 5½-digit Model 6485 Picoammeter combines Keithley’s expertise in sensitive current measurement instrumentation with enhanced speed and a robust design. With eight current measurement ranges and high speed autoranging. this cost-effective instrument can measure currents from 20fA to 20mA. taking measurements at speeds up to 1000 readings per second. The Model 6485’s 10fA resolution and superior sensitivity make it well suited for characterizing low current phenomena. while its 20mA range lets it measure currents high enough for applications such as measuring 4-20mA sensor loops. Although it employs the latest current measurement technology. it is significantly less expensive than other instruments that perform similar functions. such as optical power meters. competitive picoammeter or user-designed solutions. With a price that’s comparable to a general purpose DMM. the Model 6485 makes picoamp-level measurements affordable for virtually any laboratory or production floor.
