ETCR^® ETCRMETER^® 

EM3700 Equipotential Bonding Resistance Tester, also known as DC Low Resistance Tester, which is used for measuring the eauipotential bonding resistance in constructions and metal components(lightning belt, grade beam, structure, protection, floor bar, water pipe, radiator, toilet, doors and Windows, balcony, kitchen and other objects), also can measure the contact resistance of circuit breaker, switch and socket contacts as well as a variety of coil resistance, diverter resistance and metal riveting resistors for vehicles, ships and aircraft, resistance of the welding contacts, the parallel connection resistance of storage battery, the contact resistance of the distributor bus(bar) and wire,etc. The instrument is equipped with large capacity lithium battery pack, especially for outdoor construction site to use. lt is widely used in construction quality inspection station, supervision company, construction unit, lightning protection company, electric power department and ship locomotive factory, etc.

ETCR EM3700 Equipotential Bonding Resistance Tester consists of the host, monitoring software, test leads, chargers, and USB communication wires. The instrument adopt with precision four-wire method for testing, which is accurate and reliable. It also has the functions of alarm function, clock function, and test wire length. 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.
