Product IntroductionProduct Introduction
A good grounding system is an important guarantee for the safe and reliable operation of power, telecommunications, and electrical equipment. The size of the grounding resistance is the basis for evaluating the quality of the grounding system. Accurate, fast, simple, and reliable methods for measuring grounding resistance have become an urgent need for technological progress in the field of lightning protection and grounding. The HZQX-J dual clamp multifunctional grounding resistance tester is suitable for telecommunications, power, meteorology, computer rooms, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc.
The HZQX-J dual clamp multifunctional clamp shaped grounding resistance tester not only has the traditional function of measuring grounding resistance with auxiliary electrodes, but also has the unique function of measuring without auxiliary electrodes, which changes the traditional measurement principle and method of testing grounding resistance: using dual clamp non-contact measurement technology does not require auxiliary electrodes or isolating the grounding body from the load, achieving online measurement. Under conditions of single point grounding system and strong interference, the measurement method of using auxiliary electrodes can be adopted for measurement.

Product featuresProduct Characteristics
Suitable for any grounding location, multiple or single point grounding, can be tested normally;
●Strong anti-interference ability:
Generate high-frequency currents independently, thereby filtering out harmonic interference currents such as 50Hz and 100Hz in the mains power supply. Even in a 500KV substation environment, it can be accurately measured;
●Wide measurement range and high resolution:
The range is from 0.01 Ω to 200 Ω, with a resolution of 0.01 Ω. It can also accurately measure grounding resistance below 0.7 Ω;
●Large jaw design:
Jaw diameter 50mm (standard configuration), suitable for using flat iron/steel as grounding lead, special jaw size can be customized according to customer requirements;
●Large capacity data storage:
Can store 200 sets of measurement data;
●Easy to operate, single person assignment:
Full Chinese operation interface, small size, light weight, explosion-proof portable case, easy to carry for field measurement.
