Used KEITHLEY 6485 #9082417 for sale

KEITHLEY 6485 is a three- and four-wire low-current picoammeter designed for the precise measurement of low-level DC current down to femtoamperes. It offers an extended range of current measurement, from 200nA to 10mA, with a high resolution of 0.1fA, as well as high speed, low noise, and precision measurements. This allows its users to accurately characterize devices and components operating at very low current levels, including photodetectors, photo diodes, Hall effect devices, and thermocouples. The instrument features a high-voltage terminals that allow users to make accurate low current measurements in an environment of up to 50 volts without sacrificing the instrument's accuracy or resolution. It has both isolated and non-isolated input options to protect against external interference and ensure reliable results. In addition, 6485 features a 10-volt source mode that allows it to function as a limited sourcemeter, capable of improving the precision of current measurements when sourcing to properly characterize devices that require an external bias voltage. The instrument also includes several features to help minimize noise and ensure the highest accuracy and resolution during measurements. These include low-pass filters and area blanking for protection against high-frequency noise sources. Also, KEITHLEY 6485 can be equipped with an external current pre-amplifier to increase its sensitivity and dynamic range when measuring low current signals. The instrument is also designed to be user-friendly, with a front panel with easy-to-use menu navigation and an intuitive front panel display that provides help messages and graphically displays measurement results. It also features a built-in calibration feature to ensure accuracy and the ability to store instrument settings and save measurements to a PC for further analysis. Overall, 6485 provides a reliable, accurate, and high performance platform for low current measurement applications. Its simple user interface, extended measurement range, and built-in protection and calibration features make this instrument an ideal choice for users looking for reliable current measurement results.
