EM2200 High-End Multifunction Clamp-On Earth Ground Resistance Tester Clamp Earth Resistance Tester, also known as clamp type earth resistance tester, single clamp earth resistance tester, loop resistance tester, lightning protection grounding resistance meter and lightning protection ground resistance instrument, which is used for measurement of earth resistance, loop resistance and grounding fault judgement.When measuring grounded systems with loops, it does not require disconnecting the ground down-conductor and using auxiliary ground electrodes, which is safe, fast and convenient to use.The clamp earth resistance tester is widely used in earth resistance  and loop resistance measurement in power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment.The long clamp is particularly suitable for applications with flat steel grounding.
The EM2200 can measure ground faults that cannot be detected by traditional methods and can be applied in situations that traditional methods are unable to measure, because the clamp earth resistance tester is measuring the comprehensive value of the earthing electrode resistance and the earthing lead resistance. 
The EM2200 high-end multifunctional clamp-on grounding resistance tester has multiple display modes combined, allowing for simultaneous display of resistance + current, resistance + time, and current + time. It has a wider measurement range, can store 999 sets of data, has lower power consumption, and uses a large-capacity lithium battery. The accompanying monitoring software has functions such as online real-time monitoring, historical query, software alarm settings, historical data reading, saving, and reporting.
ETCRMETER is a high-end brand of ETCR. All products are manufactured by ETCR, which also provides technical support and after-sales service.
