Electromagnetic Features IEC61326(EMC) Protection Type IEC61010-1 (CAT Ⅲ 300V 、 CAT IV 150V 、 Pollution 2), IEC61010-031, IEC61557-1 (Earth resistance), IEC61557-5 (Soil resistivity), JJG 366-2004
ERT-40R Earth Resistance Soil Resistivity Tester is specially designed and manufactured for on-site measurement of earth resistance, soil resistivity, earth voltage. Apply digital processing technology, precision 4-wire method, 3-wire method and simple 2-wire method to measure grounding resistance; Adopt FFT (fast Fourier transform) technology, AFC (automatic frequency control) technology, automatic identification of interference and selection of measurement frequency, to minimize the impact of interference, provide more accurate earth resistance value. With unique anti-interference ability and environmental adaptability, high repeated test consistency, ensuring high precision, high stability and high reliability for long-term measurement. The tester case is made of waterproof protection box, anti-collision, anti-drop, waterproof (protection grade IP65), strong and durable, and also equipped with a large-capacity rechargeable lithium battery pack, especially suitable for outdoor construction. Widely used in power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment, such as grounding resistance, soil resistivity, grounding voltage. ERT-40R Earth Resistance Soil Resistivity Tester is composed of host machine, monitoring software, testing wires, auxiliary ground pillars, 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 300 sets of data, fulfilling historical inquiry and online real-time monitoring through monitoring software, dynamic display, alarm indicator, and with the functions as historical data access, reading, preservation, report forms, printing and so on.
