ETCR3000 DigitalEarth Resistance Tester specially designed and manufactured for the field measurement of ground resistance, adopts digital and micro-processing technology, 3 wire or 2 wire method to measure ground resistance, with unique calibration function for wire resistance, anti-interference ability and environmental adaptability, to ensure the long-term measurement of high precision, high stability and reliability; 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 outdoor construction site to use.It is widely used in measuring ground resistance of electric power, telecommunication, meteorology, oil field, construction, lightning protection and industrial electrical equipment.

ETCR3000 DigitalEarth Resistance Tester has the unique function of wire resistance calibration, and it is more accurate to measure the low value ground resistance in the field, which can avoid the error caused by the change of wire resistance in the test line for a long time usage.It can avoid errors caused by incomplete insertion of test line into instrument interface or bad contact.It can avoid the error caused by the user to change or lengthen the test line.

ETCR3000 Digital Grounding Resistance Tester is composed of host machine, monitoring software, test wires, communication wires etc. The large LCD display of host machine, with white backlight and bar graph indicating that can be seen clearly. At the same time it can store 400 sets of data, realize historical inquiry and online real-time monitoring by monitoring software, dynamic display, with the indicator of max/min/average value, and with alarm value setting and  alarm indicator functions, and with the functions as historical data access, reading, preservation, report forms, printing and so on.
