Please feel free to buy high quality equipment for sale here from our factory. Good service and reasonable price are available.<strong>Introduction<\/strong>HZRC3000B soil resistivity tester is specially designed and manufactured for on-site measurement of grounding resistance, soil resistivity, grounding voltage, and AC voltage. It adopts digital and micro-processing technology, precise 4-wire method, 3-wire method and simple 2-wire method. Method to measure ground resistance, import FFT (Fast Fourier Transform) technology, AFC (Automatic Frequency Control) technology, automatically identify interference and select the measurement frequency, minimize the impact of interference, and provide more accurate ground resistance. It has unique anti-interference ability and environmental adaptability, and good consistency of repeated tests, ensuring high precision, high stability and high reliability of long-term measurement. It is widely used in electric power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment, such as ground resistance, soil resistivity, ground voltage, AC voltage measurement.<\/p>\n<p>&nbsp;<\/p>\n<\/article>\n<table class=\"table\" style=\"height: 691px;\" width=\"967\">\n<tbody>\n<tr class=\"firstRow\">\n<td width=\"151\">\n<div>Function<\/div>\n<\/td>\n<td width=\"504\">Measurement of 2\/3\/4-pole earth resistance, soil resistivity, earth voltage, AC voltage<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Power Supply<\/div>\n<\/td>\n<td width=\"504\">DC 9V(Zi-Mn dry battery R14S 1.5V 6 PCS, continuous standby for 300 hours )<\/td>\n<\/tr>\n<tr>\n<td rowspan=\"2\" width=\"151\">\n<div>Measurement Range<\/div>\n<\/td>\n<td width=\"504\">Earth Resistance: 0.00\u03a9-30.00k\u03a9<\/td>\n<\/tr>\n<tr>\n<td width=\"504\">Soil Resistivity: 0.00\u03a9m-9000k\u03a9m<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Measuring Mode<\/div>\n<\/td>\n<td width=\"504\">Precise 4-pole measurement, 3-pole measurement, simple 2-pole measurement<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Measuring Method<\/div>\n<\/td>\n<td width=\"504\">\n<div>Earth Resistance: rated current change-pole method, measurement current 20mA Max<\/div>\n<div>Soil Resistivity: 4-pole measurement (Wenner method)<\/div>\n<div>Earth Voltage: average rectification(between P(S)-ES)<\/div>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Test Frequency<\/div>\n<\/td>\n<td width=\"504\">128Hz\/111Hz\/105Hz\/94Hz(AFC)<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Short-circuit Test Current<\/div>\n<\/td>\n<td width=\"504\">AC 20mA max<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Open-circuit Test Current<\/div>\n<\/td>\n<td width=\"504\">AC 40V max<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Test Voltage Wave<\/div>\n<\/td>\n<td width=\"504\">Sine wave<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Electrode DistanceRange<\/div>\n<\/td>\n<td width=\"504\">Can be set 1m-100m<\/td>\n<\/tr>\n<tr>\n<td rowspan=\"2\" width=\"151\">\n<div>Shift<\/div>\n<\/td>\n<td width=\"504\">Earth Resistance: 0.00\u03a9-30.00k\u03a9, automatic shift<\/td>\n<\/tr>\n<tr>\n<td width=\"504\">Soil Resistivity: 0.00\u03a9m-9000k\u03a9m, automatic shift<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Backlight<\/div>\n<\/td>\n<td width=\"504\">Blue screen backlight, suitable for dim places<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Display Mode<\/div>\n<\/td>\n<td width=\"504\">4-digital super-large LCD display, blue screen backlight<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Measuring Indicator<\/div>\n<\/td>\n<td width=\"504\">During measurement, LED flash indicator, LCD count down display, progress bar indicator<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>LCD Frame Dimension<\/div>\n<\/td>\n<td width=\"504\">128mm\u00d775mm<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>LCD Window Dimension<\/div>\n<\/td>\n<td width=\"504\">124mm\u00d767mm<\/td>\n<\/tr>\n<tr>\n<td width=\"151\">\n<div>Dimension<\/div>\n<\/td>\n<td width=\"504\">L\u00d7W\u00d7H: 215mm\u00d7190mm\u00d795mm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Introduction ETCR3000B soil resistivity tester is specially designed and manufactured for on-site measurement of grounding resistance, soil resistivity, grounding voltage, and AC voltage.
