What Is an Earth Tester?
An Earth Tester, also known as an Earth Resistance Tester or Ground Tester, is used to measure the resistance of the earth connection in electrical installations. Proper earthing ensures:
-
Safe dissipation of fault currents
-
Protection against electric shocks
-
Prevention of equipment damage
-
Compliance with safety regulations
The Mextech DET1620 is engineered for accurate and dependable earthing measurement in various environments.
How the DET1620 Earth Tester Works?
The tester injects a small test current into the ground using auxiliary spikes and measures the resulting voltage drop. Using this method, it calculates the earth resistance value with high precision.
Key Measurement Methods Supported:
1. 3-Pole Measurement
Ideal for general grounding inspection.
2. 4-Pole Measurement
Provides highly accurate readings for industrial installations.
Both methods ensure solid and accurate earth resistance readings.
