2461-EC Graphical PotentiostatDatasheet KEITH LEY Key Features • Perform Cyclic, Squarewave, Galvanic Voltammetry, Chronoamperometry, and Chronopotentiometry • Simplified user interface for faster test setup and analysis of results • Real-time plotting of voltammograms on the front panel • Analytical graph cursors for immediate analysis of results current without the need for a PC • Create libraries of reusable, customizable experimental software with built-in scripting The 2461-EC Graphical Potentiostat brings speed, flexibility, and simplicity right to your fingertips. Its innovative graphical user interface (GUI) and advanced, capacitive touchscreen technology allow intuitive usage and minimize the learning curve to enable researchers, scientists, and students to learn faster, work smarter, and invent easier. The 2461-EC is a versatile instrument, particularly well-suited for research and development in fundamental electrochemical lab research, characterizing the next generation of materials and electrolytes, new energy storage devices, and faster, smaller sensors. • Screen capture function allows copying test results from the display to reports • Wide coverage up to 105 V, 7 A DC/7 A pulse, 100 W max. • Front panel input banana jacks; rear panel input mass termination screw connections • Context-sensitive help function minimizes learning • Front-panel USB 2.0 memory I/O port for transferring data, test scripts, or test configurations While potentiostats are excellent instruments for electrochemistry applications, they typically lack any front panel display and control knobs, often are 2-quadrant systems only, and must be completely controlled by a computer with software that is not always open for users to customize tests beyond what the software can do. The 2461-EC includes a wide range of voltages and currents for sourcing or measuring, pV/pA sensitivities, and high impedance sense leads with a typical input resistance of 50G ohms and only 1pA of input bias current, typically acceptable with a wide variety of reference electrodes. The 2461-EC can run internal application test scripts so electrochemistry measurements can be run without the use of an external computer. Results are immediately displayed right on the instrument front panel touchscreen. Connecting the 2461-EC to a 2-, 3-, or 4-electrode cell is simple with the included translation cable.

Mass screw terminal connections Rear panel connections are optimized for signal integrity. Free Instrument Control Start-up Software The 2461-EC can be repurposed for applications beyond electrochemistry as a general purpose lab tool, e.g. I-V testing, leakage testing, battery charge/discharge profiling, etc. KickStart, Keithley’s instrument control non-programming start-up software, lets users start taking measurements in minutes for typical current versus voltage applications. In most cases, users merely need to make quick measurements, graph the data, and store the data to disk to...
