Dual-clamp Multifunction Earth Resistance Tester Electrical Test Equipment
Product Description:
HZJD-610 Dual-clamp earth resistance tester is suitable for telecommunication, electric power, meteorology, computer room, power distribution circuit, power transmission circuit, gas station, factory grounding network, lightning rod, etc.. With the unique function of no auxiliary electrode measurement, change the traditional measuring principle and test method of grounding resistance. Using double jaw non contact measurement technology, no need auxiliary electrode, and isolation of grounding body and load, realizes the on-line measurement. In the single point grounding system, strong interference conditions, can be measured by way of playing the auxiliary measuring electrode.
Product Features:
◆ Dual clamp and ground achor two measurement methods: Suitable for any ground site, multi-point or single point grounding.
◆ Strong anti-interference ability: Even in the 500KV substation environment, it can accurately measure.
◆ High resolution: measurement range from 0.01Ω~200Ω, resolution 0.01Ω, can accurately measure the grounding resistance less than 0.7Ω.
◆ Big jaw design: diameter 50mm(standard), special size according to customer’s requirements.
◆ Large-capacity data storage: can storage 200 groups test data.
