ETCR2800C Multifunctional non-contact resistance online tester is that our company dedicates another high-tech product to grounding resistance test for technical research results for more than ten years. The detector takes over the production of weather fastness material, temperature resistance, cold-resistant, corrosion prevention, fire prevention. The structure of the detector is strict and firm, against rain, dustproof, installation and outdoor use. › See more product details; Product description Specifications: Power supply: DC 6 V ~ 9 V, 5 0 mA max.
