China Resistance Tester Three-Wire Resistance Tester Digital Earth Resistance Tester

HT3010 Digital Ground Resistance Tester

HT3010digital grounding resistance tester, also namethe three-wire grounding resistance tester, grounding resistance meter, etc., it is a commonly used meter for measuring grounding resistance. It uses a large LCDGeographic Surveying Instrument gray screen backlight display and microprocessor technology to meet the requirements of two-wire and three-wire test resistance It is a new generation of grounding measurement instrument that replaces traditional rocking table measurements. Suitable for telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding networks, lightning rods and so on. Instrument testing is precise, fast, simple, stable and reliable

HT3010digital grounding resistancetester is controlled by a microprocessor, it's large LCD gray screen display resistance value at a glance .It canstore 500 sets of dataat the same time, resistance measurement range 0.01Ω ~ 3000Ω, grounding voltage range: 0 ~ 600V,with the value of maintaining and alarm tips and other functions.
