Multimeters are devices that measure multiple electrical values including voltage (volts), current (amps), and resistance (ohms). They are considered an essential tool for diagnosing issues, testing circuits, and ensuring electrical safety in electrical components and circuits. Multimeters are available in various types, each tailored to specific needs from basic models for beginners, through to advances, precision multimeters for professionals who require a broader range of measurement capabilities.
Our comprehensive range of multimeters have been chosen for their high-quality components and accuracy, sourced from leading brands in the industry. Browse our range today which includes Fluke Multimeters, Keysight Multimeters and our own RS PRO Multimeters and find your ideal multimeter solution.

What is a multimeter?
The multimeters purpose is to check the electrical resistance within a circuit. They are available in two different types; analogue or digital. Within the device there are many tests that can be performed, no two multi-meters are the same and the functions can vary with the price so it's important to have a good quality multimeter with multiple functions if you are an electronic engineer and electrician.
What are the main types of multimeters
- Analogue Multimeters - relatively simple to use, but have limited features and functions
- Digital Multimeters (DMMs) - come in various forms including handheld, benchtop, and clamp meter versions, each catering to specific measurement requirements.
- Bench multimeters - more suitable for the workshop and laboratory-based engineers and technicians who need a reliable instrument for maintenance, test, or repair tasks
What is the difference between an analogue and digital multimeter?
Analogue multimeters use a needle scale to show their readings whereas digital multimeters have a numeric display. As the needle can move over time due to fluctuations caused by the flow of the electricity, the needle will move over time. As technology has advanced, digital multimeters (DMM) have become more popular as they have the ability to measure with greater accuracy and the LCD display is easy to read.
Checks performed by multimeters include:
- AC or DC voltages
- Continuity of electrical components
- Current in circuits
- Diode testing
- Some advance models may measure frequency, temperature, capacitance and have True RMS voltage and current readings
- Auto-ranging capabilities which automatically selects the measurement range
Multimeters typical applications
Multimeters are used across a range of industries, environments and applications, including electronics testing, domestic, commercial, and industrial electrical wiring installation, and automotive servicing.
