Description
CHEKMAN Socket Earth Tester TK-21
An earth tester measures the resistance of an earth electrode to the mass of earth — the figure that decides whether a fault will clear.
Key Features
- Three-pole method needs two spikes; clamp-on types work on a loop without them
- Soil moisture moves the reading — record conditions with the result
- Socket testers check an installed outlet in seconds but do not replace a full test
