سایر توضیحات
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 func
