    Martindale Clamp Meters

    Martindale Clamp Meters are electrical testing instruments designed to measure current without breaking the circuit. They achieve this by using a jaw that clamps around the conductor, creating a magnetic field proportional to the current flowing through it. This magnetic field is then converted into an electrical signal that the meter can display.

    Martindale is a well-respected brand of clamp meters, known for their quality, durability, and accuracy. They offer a wide range of clamp meters to meet the needs of a variety of users.

    Who uses clamp meters?

    Clamp meters are essential tools for electricians, technicians, and anyone who needs to measure safely and accurately current in a variety of applications. Some of the most common uses for clamp meters include:

    • Troubleshooting electrical circuits – to identify overloaded circuits, faulty components, and ground faults.
    • Verifying proper installation of electrical equipment
    • Performing preventive maintenance - used to detect potential problems with electrical equipment before they become serious.
    • Measuring energy consumption

    Types of clamp meters include:

    • AC current clamp meters - designed to measure alternating current (AC).
    • DC clamp meters - measure direct current (DC).
    • True RMS clamp meters - can accurately measure both AC and DC currents, even if the waveform is distorted.
    • Leakage clamp meters – can measure small leakage currents, such as those that can occur in ground fault circuits.

    When choosing a Martindale clamp meter, it is important to consider the following factors:

    • The type of current you need to measure (AC, DC, or both)
    • The maximum current you need to measure
    • The accuracy you need
    • The features you need, such as True RMS measurement, peak hold, and data logging
