    Clamp Meter

    As one of the necessary test tools for electricians' daily maintenance work, the clamp meter is mainly used for the occasion of measuring the current without disconnecting the circuit. The clamp meter is used to measure the related parameters of circular such as current, voltage and resistance. Some models can also measure frequency, capacitor and temperature. The measured data is displayed directly on the LCD display of clamp meter and the data can be held for easy reading and recording. The new smart clamp meter also features automatic range, TRMS and NCV functions. According to the current measurement principle, the clamp meter can be divided into AC clamp meter (only AC current can be measured) and AC/DC clamp meter (both AC current and DC current can be measured through function selection).
    ATO clamp meters are CE/FCC/ROHS certified. The more you buy at one time, the cheaper the price of the digital clamp meters.
