BECKMAN INSTRUMENTS 5713-1489-0 RIOK L..1/3/5 POTENTIOMETER VAR RESISTOR 3-LEVEL NEW OLD STOCK there were part of my late partner’s electronics supplies. I do not have the equipment or knowledge to test them, so they are being sold as untested. They appear to be in good physical condition (please see photos for details), but I cannot guarantee functionality. Sold as-is, no returns due to inability to test. I would recommend a look at my other stuff. it's coming more. Thank you for understanding.
The Beckman Instruments potentiometer variable resistor is ideal for applications that require precise control and calibration of resistances, finding its most suitable use in various scientific instruments, electronics, and instrumentation.
