HT3010 Digital Ground Resistance Tester
I. Product Introduction
HT3010 digital grounding resistance tester, also name the three-wire grounding resistance tester, grounding resistance meter, etc., it is a commonly used meter for measuring grounding resistance. It uses a large LCD 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
HT3010 digital grounding resistance tester is controlled by a microprocessor, it's large LCD gray screen display resistance value at a glance .It can store 500 sets of data at 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.
