Economical Earth Resistance Tester We need a proper grounding to benefit our daily activities and facilities. It helps us not to hurt due to faulty equipment or home appliance installation. Damage from lightning strikes and induced voltages also hazarded to us. Over time, ground systems can degrade or become ineffective. The risks from ground system deterioration include potentially deadly electrical shock situations, equipment damage and heat build-up on a single piece of electrical equipment that is dangerous to our community. All British Standard Tester ER models (ER-80A / 80M / 81 / 82M / 83A) can perform Earth resistance tests (using the 2, 3 & 4 terminals rod method) to determine the connection from equipment to the grounding system for safety assurance.
