Keithley 2750 Multimeter Data Acquisition Switch System

The Keithley 2750 Multimeter Data Acquisition Switch System combines a true 6½-digit DMM, integrated data logger, and configurable switch matrix in a single mainframe. This instrument delivers high-accuracy measurements across 14 functions while managing up to 200 differential input channels through five modular slot architecture. Purpose-built for automated test environments, it handles production testing, device characterization, and R&D applications requiring synchronized measurement and switching operations.
