Introduction:

Digital equalpotential tester is also known as micro-ohmmeter, ohmmeter, DC grounding resistance tester, using the most microprocessor technology, four-wire test, safe and reliable.

It is a special instrument for detecting equipotential bonding quality between metal components of objects such as housings, lightning protection belts, ground beams, structures, cabinets, steel bars, pipes, windows, guardrails, radiators, and assembly lines.

It can also measure the resistance of the connection conductors between various electrical equipments and earth ground, the DC resistance of transformers, and also can measure the contact resistance of switches and socket contacts, coils, metal wires, welding points and other low-value resistances.

Widely used in telecommunications, electric power, meteorology, computer room, oil field, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc. It also has the function of measuring DC voltage and AC voltage.

Digital equipotential tester consists of a host computer, monitoring software, test leads, and communication lines.The mainframe large-screen LCD display is clear at a glance.

Can store 500 sets of data, resistance measurement range: 0.0001 Ω ~ 30K Ω, DC voltage range: 0.0 ~ 1000V, AC voltage range: 0.0 ~ 750V.

The monitoring software has on-line real-time monitoring and historical query functions, dynamic display, alarm value setting and alarm indication function, and functions such as reading, reviewing, saving, reporting and printing of historical data.
