Inspection pits are primarily used for regular resistance measurement of grounding systems. Before measuring resistance, remove the inspection pit cover and connect the measurement instrument wire to the grounding conductor.
They are widely used in grounding-related projects, including protective grounding, anti-interference grounding, lightning protection grounding, and anti-static facilities. Inspection pits provide great convenience for real-time monitoring of grounding efficiency and testing grounding effectiveness.
Different sizes and materials of inspection pits are available.
