INTRODUCTION

MEWOI7600 series Clamp Leakage Current Meter is specially designed and manufactured for measuring AC leakage current and current. The meter adopts unique CT technology and digital integration technology, has the characteristics of small size, high precision and perfect function. Widely used in electric power, communications, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields.

MEWOI-MEWOI7600 series Clamp Leakage Current Meter clamp jaw made of permalloy and adopts magnetic shielding technology, it is almost not affected by the external electromagnetic field, ensuring high precision, high stability and high reliability of uninterrupted measurement long time. The clamp meter has test functions such as true virtual value measurement, filtering function, maximum/minimum /average value, harmonics, distortion rate, etc., which can test  the current in the frequency range of 40Hz to 1kHz. The clamp meter also has functions such as backlight, flashlight, data hold, and Bluetooth communication. The clamp meter uses a rechargeable large-capacity lithium battery, which is a new type of necessary tool for electrician safety testing.
