Used KEITHLEY 487 #9364149 for sale

KEITHLEY 487 Picoammeter is a precision current-measurement instrument that is versatile, reliable and user-friendly. It offers high-precision current measurements over a 1000:1 dynamic range and features low-current resolution down to 200 fA with 1 fA digital resolution. The four selectable modes - DCV, 4W, 2W, and 4-Terminal - allow the user to select the most appropriate measure technique for the application. 487 is primarily used for low-level current measurements in laboratory and production environments. For instance, tests for leakage current, saturation current, and component charactersistics are routinely performed by injection of bias signals into the circuit under test and measuring the resulting current. The high-resolution display (8x7 Digits) and selectable analog bargraph offer detailed current information. KEITHLEY 487 provides several features which enable stable, accurate measurements, including a unique High-stabilization mode, whereby long integration times, low-pass filtering, and on-board temperature compensation can be utilized to achieve high-accuracy results. Additionally, 487's Trigger TTL Input allows for external triggering and synchronization of data acquisition. KEITHLEY 487's backlit LCD display ensures that measurements results are easily readable. Additionally, 487 offers interactive menus with shortcut keys and keys for direct value selection which simplify operation and improve user experience. The Ethernet and RS-232 communications ports make it simple to connect KEITHLEY 487 to a PC or data acquisition system. Thanks to the software utility like I-V Studio, KEITHLEY BenchLink Data Logger Plus and the TSP-Link interactive commandset, device integration and data streaming is effortless. Overall, 487 Picoammeter is a reliable, precision, and easy-to-use device for low-level current measurements. Its wide dynamic range, low noise floor, and reliable outputs make it suitable for a wide range of applications across the laboratory and production environment.
