SMART SENSOR ST4100 0mA-30A Ground Earth Resistance Tester 0.01-500Ω 500 Groups

Product Description

The clamp-shaped ground resistance tester is controlled by a microprocessor to accurately detect the ground resistance. It uses a rapid filtering technology to minimize the interference. It is a commonly used and necessary instrument for telecommunication, electric power, meteorology, engine room, oil field, electromechanical installation and maintenance as well as industrial enterprise departments using electric power.

Features:
Easy to Operate: When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, safer and faster.
Precision Clamp Head Design: Using precision iron core and winding, stable, precise and strong anti-interference. Clamp Size: Φ1.26"(32mm), large jaws with double insulation for extra safety.
Data Storage Function: 500 sets of measurement results can be recorded, the "MEM" storage indication, flashing the "MEM" symbol indicating that the storage is full.
Multi Practical Functions: New design, panel operation with 6 buttons, better performance. With real-time clock, data storage, data access, alarm, automatic shutdown and other functions.
Widely Used: It is suitable for measuring all kinds of telecommunications, electric power, meteorology, machine room, oil field, power distribution lines, tower transmission lines, gas stations, factory grounding network, lightning rob and other grounding resistance.
