Project Description
Product Features:
The structure of the digital ground resistance tester uses high-strength aluminum alloy as the case. In order to prevent power frequency and radio frequency interference, the circuit adopts a phase-locked loop synchronous tracking detection method and is equipped with a switched capacitor filter to make the meter have a better anti-interference ability.
This digital grounding resistance tester does not require manual balance adjustment. It has a 3 (1/2) LCD display. Besides to ground resistance, it can also measure low-resistance conductor resistance, soil resistivity and AC ground voltage.
Using DC/AC conversion technology to convert DC into AC low-frequency constant current for easy measurement
Product nicknames: digital earth ground resistance tester, digital ground resistance tester, ground resistance, ground meter, ground resistance meter, ground resistance meter, ground resistance tester, ground stake type ground resistance tester, digital ground resistance meter, portable Ground resistance tester, digital ground resistance meter
Digital grounding resistance tester, grounding resistance meter, grounding meter are used to measure the grounding resistance value of various devices in electric power, communication, railway and industrial and mining enterprises. At the same time, the digital ground resistance tester can measure soil resistivity and ground voltage.
This digital grounding resistance tester does not require manual balance adjustment. It has a 3 (1/2) LCD display.
In addition to ground resistance, it can also measure low-resistance conductor resistance, soil resistivity and AC ground voltage. If the test circuit fails, the meter shows “1” for overflow, which is in line with conventional measurement habits
