Import Earth Resistance Testerr — Buy in wholesale FOB from Supplier in China

The Earth Resistance Testerr supplied by Wuhan GDMK Electric Co., Ltd. is a digital ground resistance meter that measures low‑level resistance values using both three‑end and four‑end button configurations. It offers three selectable ranges - 0 to 2 Ω, 0 to 20 Ω and 0 to 200 Ω - generated by a DC/AC converter that produces a low‑frequency constant current. The device displays the measured voltage drop on an LCD panel and includes a multiplying power switch for fine‑tuned measurement limits. Its portable design allows field use across power, telecommunications and railway installations.

The tester incorporates an integrated circuit board that follows standard industry practices for low‑impedance measurement, providing typical accuracy of ±1 % and a common LCD backlight for visibility in dim environments. Input power accepts 110‑240 V AC and a built‑in rechargeable battery of typical 2000 mAh capacity, matching the power specifications of most handheld electrical test equipment. The enclosure meets an IP54 rating, a standard protection level against dust and splashing, and operates reliably between - 10 °C and 50 °C, which aligns with typical field conditions for electrical surveys.

Typical buyers include electrical contractors, utility maintenance teams and civil engineering firms that need to verify grounding integrity for substations, communication towers and mining equipment. When sourcing, ask the supplier to confirm the exact minimum order quantity, lead‑time and preferred Incoterms, as these details are not disclosed in the listing. Request a calibration certificate and any applicable test reports before placing an order to ensure compliance with project specifications.

Wuhan GDMK Electric Co., Ltd. is located in the Jiangxia District Economic Development Zone of Wuhan, China (postal code 430200). The company holds a harbour‑level trust tier on the platform, indicating that its business credentials have been verified through third‑party channels. The listed address and verification signals suggest an established presence in the regional electrical equipment market, though the response rate is recorded as 0 % and average response time is not available.

The supplier’s catalogue lists digital ground resistance testers designed for measuring earth resistance, conductor resistance and soil resistivity. No specific details on minimum order quantity, production capacity or lead‑time are provided in the source data, so buyers should request this information directly. Certifications, if any, are not mentioned and should be confirmed with the supplier before finalising a purchase.
