Analysis Instruments

A potentiometer is a three-terminal variable resistor commonly used to adjust voltage levels, tune electrical circuits, and control electronic devices. It functions as a voltage divider, allowing users to vary resistance in a circuit and thereby control current flow or signal strength. Potentiometers are essential components in applications such as audio equipment, instrumentation panels, power supplies, microcontroller input systems, and industrial automation controls.

There are several types of potentiometers available, including rotary potentiometers, slide potentiometers, and digital potentiometers, each designed to suit specific use cases. Most commonly, rotary potentiometers are used in volume control knobs and tuning dials, while slide types are found in audio mixers and fader controls.

Made with durable carbon film, cermet, or wire-wound elements, potentiometers are designed for long-term performance and repeatable accuracy. Some models include a built-in switch for ON/OFF control in compact designs, and others are sealed for dust or moisture protection, ideal for harsh environments.
