Non-contact sensing is extremely safe. Real-time data is reported through voice. Fourteen-digit display + 400A large current precise measurement. One-click switchable range. It can also measure voltage, resistance, and capacitance. Capable of handling various electrical operations in multiple scenarios, ensuring precise measurement and ease of use!

400A High Current + 35mm Large Clamping Mouth, "Large" means it has the capability for measurement
It supports the measurement of up to 400A of alternating current. With its 35mm large clamping mouth design, it can easily hold various cables, whether they are thick industrial wires or dense multi-strand conductors, all "in one clamp". The high-precision measurement chip ensures accurate and stable data in high current scenarios, completely eliminating the awkwardness of "inaccurate measurement due to overcurrent, or inability to hold due to too small clamping mouth". Industrial-level detection requirements can also be easily met.
With voice announcement! This high-precision clamp-type ammeter redefines the "safety" and "efficiency" of electrical measurement. For electricians, the "accuracy" and "convenience" of measurement tools directly affect job safety and efficiency. The high-precision clamp-type ammeter with voice announcement, with its "non-contact sensing + voice reading + all-in-one measurement" hardcore configuration, has become the "safety and efficiency double trump card" for electricians.
It is equipped with non-contact sensing technology, allowing for current measurement without breaking the wire or cutting off the power supply. Simply place the clamp over the wire and you can safely read the current data, eliminating the risk of electric shock from the source. It is even more considerate with the intelligent voice announcement function, which provides real-time voice announcements of the measurement results. Even if you are working in a noisy construction site, workshop, or a narrow space with obstructed vision, you can promptly grasp the data through clear voice, without having to remove your hands from the work point, significantly enhancing the convenience and safety of operation.
The accuracy and range performance are also excellent. The four-digit half-high-definition display is combined with a 400A large current measurement capability, capable of accurately capturing currents ranging from milliamps to industrial-level heavy loads. From micro-amp levels to industrial-level heavy loads, it can precisely capture data with negligible error, providing "millimeter-level" reference for circuit fault diagnosis and equipment load detection. The operation is also "dumbbell-style" friendly, with a one-click switch to manual range, eliminating the need for repeated adjustments. Even beginners can master it in an instant, completely eliminating the cumbersome operations of traditional instruments.
Functionally, it is undoubtedly a "multi-purpose" tool: in addition to current measurement, it can also "handle all parameters" such as voltage, resistance, and capacitance, truly achieving "one machine replacing multiple instruments", allowing you to handle scenarios like distribution equipment maintenance, motor maintenance, and home circuit troubleshooting with ease. From the component design perspective, high-insulation test probes, tightly fitting clamps, and anti-slip dial buttons, every detail serves "safe operation" and "precise measurement". Even with long-term high-intensity use, it can still output stable performance.
Whether it's large equipment inspection in factories or circuit renovation in residential buildings, the high-precision clamp-type ammeter with voice announcement can become your "reliable partner" in the "voice announcement convenience", "non-contact safety", and "all-parameter all-in-one" aspects, making every circuit measurement precise, safe, and worry-free! Choose it, and you are choosing the "eye and ear combined" efficient working method, ensuring that every circuit measurement is accurate, safe, and worry-free!
