jb Capacitors Company offer Trimming Potentiometers come in a variety of sizes and levels of precision.
For example, JBR-3540 TWire Wound Element, multi-turn trim potentiometers exist, in which it takes several turns of the adjustment screw to reach the end value, allowing for very high degrees of accuracy. More details please check below specification.
