100A Digital Voltmeter Ammeter Battery Capacity Coulometer Power Electricity Watt-Hour Meter with Ha

The coulometer that uses the Hall sensor to measure can be installed very simply.You don't need to consider the problem of power supply. Because the Hall measurement is an isolated measurement, it will not damage the original circuit, and is N times and more reliable than the general shunt coulomb counter.Name: Coulomb counterSpecification: 100Acolour: blackMaterial: plasticPackage Contents:1 x LCD Hall Coulomb CounterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.
