Clamp meters are an electrical test tool used to measure electrical characteristics such as AC current, AC and DC voltage, resistance, continuity and more. Clamp meters are often a combination of a basic digital multimeter and a current sensor, offering a versatile electrical measurement tool. The main advantage of these devices is that allows the user to take a reading from a wire without touching it, which is safer and more convenient than other methods. Clamp meters are commonly used by:

  • Industrial maintenance technicians

  • Control technicians

  • Electricians – in-house and contractors

  • Facilities, building maintenance and HVAC technicians

  • Service organisations

Standards and Certifications:

  • EN61010-1, EN61010-2-032

  • EN61326-1

  • Overvoltage Category III 1000V and Category IV 600V

  • Pollution Degree 2

What is the benefit of using a flexible clamp meter?

Flexible clamp meters are specifically designed for access to awkward and hard to reach areas, making this unique design ideal for the types of jobs where the hard jaw clamp meters are unable to gain access to. The flexible coil can effortlessly be snaked around obstructions with ease.
