High Precision Single Jaw Ground Resistance Tester with Current Range 0.00mA-20.0A
Product Description
1.Break through the long-term self-test waiting for power-on, and enter the test immediately after power-on.
2.Break through the relay self-checking method, adopt the most advanced algorithm and digital
3.Integrated processing technology.
4. Breaking through the cumbersome problem of old products, it is more in line with the characteristics of hand-held instruments.
5.New appearance design, 6-key operation on the panel, and direct performance.
6.Added sound and light alarm function, "beep-beep-beep--" alarm sound. Added interference signal identification indication function, "beep-beep-beep--" sound prompt.
7. The measurement range is increased to 0.01Ω-1200Ω.
8. 99 groups of data are stored, the power consumption is lower, and the maximum startup and working current is less than 50mA.
9. This equipment is widely used in grounding resistance measurement and loop resistance measurement of electric power, telecommunication, meteorology, oil field, construction and industrial electrical equipment. When measuring the grounding system with loop, there is no need to disconnect the grounding lead and auxiliary electrode, which is safe and fast. It can measure ground faults that cannot be measured by traditional methods, and can be applied to occasions that cannot be measured by traditional methods, because this device measures the comprehensive value of grounding body resistance and grounding lead resistance.10. This equipment has long jaws and round jaws, as shown in the figure. The long jaw is especially suitable for the occasions where the flat steel is grounded. The C-type clamp earth resistance meter can also measure the leakage current and neutral current of the earthing system.11. The equipment has passed the explosion-proof certification and meets the requirements of GB3836-2000 "Electrical Equipment for Explosive Gas Environments". Its explosion-proof mark is Ex ia BT3Ga. Explosion-proof certificate number: CE13.2263. It can be used in corresponding flammable and explosive environments.
