Beckman Instruments 7603-R500-L.15 Helipot is a Beckman Helipot division multi-turn, wirewound precision potentiometer used for fine adjustment in laboratory instrumentation. The 7603 family is a multi-turn potentiometer, and the R500 code indicates a 500-ohm nominal resistance; the L.15 suffix identifies this particular variant. Typically used for calibration and adjustment tasks in historical Beckman equipment and other test instruments, Helipot pots are designed for high precision and repeatability.
