Product Details

Product description

HMCD earth resistivity test meter and soil resistivity tester is designed and manufactured for on-site measurement of grounding resistance, soil resistivity, grounding voltage, and AC voltage. Test current can reach 20mA. It is widely used in electric power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment.

USE advantage

1.Adopt digital and micro-processing technology, precise 4-wire method, 3-wire method and simple 2-wire method to measure ground resistance, use FFT technology, AFC technology, automatically identify interference and select the measurement frequency, so that The influence of interference is minimized, and a more accurate ground resistance value is provided.

2.the earth resistivity test meter has unique anti-interference ability and environmental adaptability, and good consistency of repeated tests, ensuring high precision, high stability and high reliability of long-term measurement.

3.This instrument consists of a host, data software, test wires, auxiliary ground rods, communication wires, etc. The special toolbox design of the host machine can withstａnd a pressure of about 200kg，to ensure high precision, high stability and high reliability for various environmental tests.

4.The host has a large LCD display with backlight and bar graph indication, which is clear at a glance. At the same time, it can store 2000 sets of data, and the historical data can be read, viewed, saved, report, and printed through the data software.
