2/3/4 Wire Handheld Battery Soil Resistivity Tester Digital Earth Resistance Tester

| Introduction：

GD-3000B soil resistivity measuring instrument supports three grounding resistance measurement modes: 2/3/4 poles. The 4-pole method can completely eliminate errors caused by line resistance and contact corrosion resistance, and ensure measurement repeatability and stability.

Widely applicable to power,

communication base stations, meteorological lightning protection, construction engineering, and industrial electrical equipment grounding acceptance testing.

| Multiple measurement modes：

| Technical Specifications：

| Asvantages：

1. Four fold anti-interference technology: AFC automatic frequency conversion+FFT filtering, additional error ≤ 5% under on-site 5V power frequency interference, stable measurement of complex electromagnetic environment in substations and distribution rooms;

2. One machine, three uses: grounding resistance+soil resistivity+ground voltage three in one, one set of equipment completes the complete testing of grounding engineering;

3. Data archiving and export: 300 sets of local storage, computer software for exporting data, generating inspection reports, and printing completion documents;

4. Humanized large screen design: analog pointer scale+digital dual display, white backlight, clear reading at night/basement construction;

5. Improve self checking function: automatically detect the grounding resistance of the auxiliary probe rod, and determine in advance whether the wiring is qualified;

6. Sound and light over limit alarm: customizable alarm threshold, automatic buzzing and screen flashing reminder for grounding resistance over limit;
