ETCR3700C Intelligent Equipotential Bonding Resistance Tester, also namedDC Low Resistance Tester, DC Resistance Tester, Ohm Meter,Milliohmmeter and so on),It is accurate and reliable adopt the precision 4-wire method for testing. It is a special meter for measuring the equipotential bonding quality between metal constructions in buildings(Lightning belt, floor beam, structure, protection, floor bar, water pipe, radiator, toilet, doors and Windows, balcony, kitchen and other objects). Also can measure all kinds of connection conductor resistance between the electrical equipment and  grounding electrode, also can measure the contact resistance of circuit breaker, switch and socket contacts as well as a variety of coil resistance, shunt resistance, transport aircraft metal riveting resistance, electric welding, contact resistance, battery in parallel connection resistance, switchboard bus bar and wire contact resistance, etc. The instrument out shell adopts waterproof protection case, anti-collision, anti-fall, waterproof (protection grade IP65), which is  strong, safe and durable, the instrument is also equipped with large capacity rechargeable lithium battery pack, especially suitable for using in outdoor construction site. It is widely used in construction quality inspection station, supervision company, construction unit, lightning protection company, electric power department, ship engine factory, etc.

The meter also has alarm function, clock function and test lead length function. which the wire resistance of a standard length is measured, and then the whole wire resistance is tested, and the length of the wire is calculated from the resistance tested twice.

ETCR3700C Intelligent Equipotential Bonding Resistance Tester consists of the host, monitoring software, test leads, chargers, and USB communication wires. The host with large LCD display, backlight, bar graph indication, clear and obvious, it can store 400 groups of data at the same time. The monitoring software has functions such as reading, reviewing, saving, reporting, and printing of historical data.
