The HZ2676 Ground Resistance and Soil Resistivity Tester,also known as a four-wire ground resistance tester or soil resistivity tester,is a commonly used instrument for testing ground resistance.It is widely used in telecommunications,power,meteorology, data centers,oil fields,power distribution lines,transmission towers,gas stations,factory grounding grids,lightning rods,etc.The instrument is characterized by its accuracy,speed,simplicity,stability,and reliability.
The HZ2676 integrates multiple grounding test functions,allowing for rapid and comprehensive measurement of various parameters in a grounding network.It replaces traditional shaking table measurement methods with a new generation of grounding measurement instruments.
1. Controlled by a microprocessor,the HZ2676 can accurately detect ground resistance,soil resistivity,and ground voltage.It uses fast filter ingtechnology to minimize interference and can store up to 500 sets of data.
2. It features an extra-large LCD grey-white backlit display and microprocessor technology,enabling two-wire,three-wire,and four-wire ground resistance and soil resistivity testing controlled by a microprocessor.
