Used KEITHLEY 237 #9115813 for sale

KEITHLEY 237 Electronic Test Equipment is designed to deal with a wide range of measurements from low level micro volts to large voltages, currents, and resistance. It is a voltage source and electrometer that combines highly resistance measurement capabilities with both step and long-term stability. It also provides an versatility to handle various applications. This 237 test equipment provides dual 4 ½ digit readouts which allow for simultaneous monitoring of two functions. The unit also offers comparison measurements such as differential voltage, relative mode, drive sense, step rise/fall time, and reciprocal. These measurements are enabled by an advanced self-test feature, which allows the user to perform internal calibrations to ensure accuracy of the measurements. The instrument is equipped with an isolated, low-noise voltage source that delivers a wide range of voltage output from 0.1V to 1100V. The accuracy of the voltage source output is improved by the use of high-stability time constants. The output resistance can also be adjusted manually and the output can switched on and off as needed. The current monitor and control functions of KEITHLEY 237 provide high resolution readouts with a 10 µA range selectable in 10 mA steps. The electrometer input has a high input impedance (50 Tohm in common mode), which is especially important when making very low level measurements with high dynamic resistance. The instrument is very easy to use and is designed to minimize noise and overshoot. It is also easy to operate with its front-panel sequencer, which allows the user to remotely control multiple instruments from one location. 237 is designed to meet stringent safety requirements, including UL listed and CE certified components for maximum safety. It also offers special features such as built-in protection against overvoltage, power surges, and errors, as well as an auto-clear function to reset the settings. The instrument is also designed for optimal data accuracy, with its internal programmable converters to adjust for temperature and signal drift. Additionally, its digital filtering feature eliminates the need for external filters, while its clear readouts provide visibility of readings on the instrument. Overall, KEITHLEY 237 is an advanced electronic test equipment that provides a wide range of measurement capabilities and a number of other features to ensure the highest accuracy and repeatability in your measurements. Its easy-to-use design, high accuracy, and robust functions make it a great choice for any laboratory setting.
