سایر توضیحات
ERT-40R Earth Resistance Soil Resistivity Tester is specially designed and\r\nmanufactured for on-site measurement of earth resistance, soil resistivity, earth\r\nvoltage. Apply digital processing technology, precision 4-wire method, 3-wire method\r\nand simple 2-wire method to measure grounding resistance; Adopt FFT (fast Fourier\r\ntransform) technology, AFC (automatic frequency control) technology, automatic\r\nidentification of interference and selection of measurement frequency, to minimize the\r\nimpact of interference, provide more accurate earth resistance value. With unique\r\nanti-interference ability and environmental adaptability, high repeated test consistency,\r\nensuring high precision, high stability and high reliability for long-term measurement.\r\nThe tester case is made of waterproof protection box, anti-collision, anti-drop,\r\nwaterproof (protection grade IP65), strong and durable, and also equipped with a\r\nlarge-capacity rechargeable lithium battery pack, especially suitable for outdoor\r\nconstruction. Widely used in power, telecommunications, meteorology, oil fields,\r\nconstruction, lightning protection and industrial electrical equipment, such as\r\ngrounding resistance, soil resistivity, grounding voltage.\r\nERT-40R Earth Resistance Soil Resistivity Tester is composed of host\r\nmachine, monitoring software, testing wires, auxiliary ground pillars, communication\r\nwires etc. The large LCD display of host machine, with white backlight and bar graph\r\nindicating that can be seen clearly. At the same time it can store 300 sets of data,\r\nfulfilling historical inquiry and online real-time monitoring through monitoring software,\r\ndynamic display, alarm indicator, and with the functions as historical data access,\r\nreading, preservation, report forms, printing and so on.
