Digital Earth Clamp Meter Model: DECT-9AM

We are reckoned as eminent Digital Earth Clamp Tester trader from India. Our Digital Earth Clamp tester induces a test current into earth systems and measures ground resistance in multi ground installations without needing to disconnect the ground. These tester come with Backlit LCD display for the improved display. Designed with flat core ends they prevent dirt to settle, ensuring measurement integrity and improved reliability.
