KEITHLEY 248 5000V 5mA High Voltage Power Supply

The Keithley 248 High Voltage Supply, designed for use in the laboratory or for test applications, features reversible polarity, excellent regulation, and low output voltage ripple. The digital displays provide accurate readings of voltage and current, and digital entry of current and voltage values allow easy, precise setting of output values. Output voltage can be set from the front panel, via a remote analog voltage, or over the standard IEEE-488 interface. Voltage and current signals are also available for remote monitoring.

*This is a Web introductory price for one calibration of the KEITHLEY 248. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.
