6485

6485 is a 5½-digit picoammeter that combines Keithley’s expertise in sensitive current measurement instrumentation with enhanced speed and a robust design. 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. Applications include beam monitoring and radiation monitoring, leakage current testing in insulators, switches, relays and other components, SEM beam current measurements, galvanic coupling measurements, optoelectronic device testing and characterization, optical fiber alignment, circuit test and analysis in DCLF circuits, sensor characterization, I-V measurements of semiconductors and other devices, nanoelectronic device characterization.
