Product introduction

MEWOI4600 Intelligent Equipotential Bonding Resistance Tester is used to measure the resistance of connecting conductors between various electrical equipment and the earth grid and the equipotential resistance between metal components in buildings. It can also measure the contact resistance of switches and socket contacts. And other low-value resistors , with micro-ohm meter function, range: 0.0010Ω~40Ω .

MEWOI4600 intelligent equipotential bonding resistance tester consists of a host, monitoring software, test lines, communication lines, etc. Host LCD display, Chinese operation interface, clear at a glance. At the same time, it has a large storage space and can store 6000 sets of data. The monitoring software has online real-time monitoring and historical query functions, dynamic display, maximum, minimum, average value indication, alarm value setting and alarm indication functions, and historical data reading, consulting, saving, reporting, printing and other functions.
