Keithley 6485/E Digital Multimeter DMM

The Keithley 6485 is a 5½ Digit Digital Multimeter (DMM) that combines current measurement instrumentation with enhanced speed and a robust design. The 6485 has 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 multimeter has a 10fA resolution and superior sensitivity, making it well suited for characterising low current phenomena, while its 20mA range lets it measure currents high enough for applications such as 4 to 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 or competitive picoammeters. With a price that is comparable to a general purpose DMM, the 6485 makes picoamp level measurements affordable for virtually any laboratory or production floor.
