Product Details

Lightning protection equipotential testerIntroduction:

The digital equipotential tester, also known as micro ohmmeter, ohmmeter, or DC grounding resistance tester, adopts the most microprocessor technology and four wire method for testing, ensuring safety, precision, and reliability. It is an instrument used to detect the quality of equipotential bonding between metal components such as equipment casings, lightning protection belts, ground beams, structures, cabinets, steel bars, water pipes, windows, guardrails, radiators, and assembly lines. It can also measure the resistance of connecting conductors between various electrical equipment and ground grid electrodes, the DC resistance of transformers, and the contact resistance of switches and socket contacts, coils, metal wires, welding points, and other low value resistances. Widely used in telecommunications, power, meteorology, computer rooms, oil fields, 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.

The digital equipotential tester consists of a host, monitoring software, testing line, communication line, etc. The host's large LCD display is clear at a glance. It can store 500 sets of data, with a resistance measurement range of 0.0001 Ω~30K Ω, a DC voltage range of 0.0~1000V, and an AC voltage range of 0.0~750V. The monitoring software has online real-time monitoring and historical query functions, dynamic display, alarm value setting and alarm indication functions, as well as historical data reading, viewing, saving, reporting, printing and other functions.
