EK-C304 Grounding Pile Type Clamp Earth Tester

EK Instruments EK-C304 is a professional grounding pile type clamp earth tester. Designed for industrial electrical measurement and field testing. Built with precision engineering and reliable components for long-term stability.

Product Function

2-wire method and 3-wire method earth resistance measurement, earth voltage measurement, AC and DC voltage measurement.

Product Features

1.The tester body is light, easy to carry and operate.
2.With the function of judging the auxiliary grounding pile, the tester can display the resistance value of the auxiliary grounding pile in testing, which can avoid the error caused by the excessive earth resistance of the auxiliary ground pile.
3.With line resistance calibration function, which can avoid the error caused by the test line not being fully inserted or poor contact. It makes the measurement of low earth resistance more accurate and reliable in the site.
4.Earth voltage measurement function.
