Product Description
Product description：
Earth ground resistance tester is a high-precision testing instrument used in various fields such as substations to test grounding resistance and related parameters.The instrument is of an integrated structure, with a built-in frequency conversion power supply module, and the output power supply is continuously variable in frequency. The frequency can be changed to 45Hz or 55Hz, the high-speed processor core is built in, and the high-end digital filtering technology is adopted, thus effectively avoiding the interference of power frequency electric field to the test and fundamentally solving the difficult problem of accurate measurement under strong electric field interference.

Feature：
1. The operation is simple. The instrument is equipped with a high-end full-touch LCD screen and an ultra-large graphical operation interface. Each process is very clear and the operator can use it without additional professional training. The whole process of measurement can be completed with one touch. It is currently a very ideal intelligent measuring device.
2. The anti-interference ability is strong. The internal variable frequency power supply module of the instrument provides the instrument measurement output power supply, the frequency can be changed to 45Hz or 55Hz, and the digital filtering technology is adopted, thus effectively avoiding various power frequency interference signals on site and enabling the instrument to realize high-precision, accurate and reliable measurement.
