Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›This earth ground resistance tester is a portable, digital instrument designed to measure grounding system impedance under high electromagnetic interference. It operates using a frequency conversion method to generate test signals at 45Hz, 50Hz, 55Hz, 60Hz, or 65Hz, or in automatic dual-frequency mode (45-55Hz or 47.5-52.5Hz), allowing accurate readings even in substations with strong power frequency noise. The device outputs adjustable test currents from 1A to 5A and voltages up to 100V, with a maximum output power of 500W.
The instrument uses a high-speed processor and digital filtering to suppress interference from ambient 50/60Hz fields, achieving a resolution of 0.0001 ohms for impedance and 0.0001 degrees for phase angle. Its measurement range spans from 0.001 ohms to 5 ohms, suitable for low-resistance grounding systems in industrial, utility, and telecom installations. The device is rated for operation between 15°C and 40°C with humidity up to 80% RH and runs on standard AC 220V ±10% input, including generator compatibility.
The device is purchased by electrical contractors, utility maintenance teams, and industrial safety inspectors who require precise grounding validation in high-noise environments. Units are shipped in protective cases with test leads, auxiliary electrodes, and a calibration certificate. Trade terms are FOB Wuhan Port, with lead times of 20 to 30 days. No certifications are listed; buyers must request IEC 61557 compliance documentation and calibration traceability directly from the supplier.

Wuhan GDMK Electric Co., Ltd. is located in the Jiangxia District Economic Development Zone, Wuhan, Hubei Province, China. The company is verified as a harbor-level supplier with no public details on factory size, production capacity, or engineering staff. The listing does not mention certifications, ISO status, or export history. There is no indication of R&D capability or product design ownership; the device appears to be manufactured to a standard specification without proprietary innovation disclosed.
The supplier has no response rate or average response time recorded, suggesting limited customer service engagement. No product manuals, test reports, or compliance certificates are referenced in the listing. Buyers should assume this is a production-based exporter of generic electrical test equipment, not a branded manufacturer. All technical claims must be verified through independent testing and certification prior to import.

Verify the instrument’s accuracy by requesting a calibration certificate traceable to a national standard, such as NIST or PTB. Confirm the test leads and electrodes meet the required voltage and current ratings for 5A output. Inspect packaging for moisture protection, as internal electronics are sensitive to humidity. Do not accept units without a serial number or model label matching the specification sheet.
Lead time is estimated at 20 to 30 days but is unconfirmed. Confirm Incoterms are FOB Wuhan Port and request container loading details. Payment terms are not stated; assume 30% advance with balance against copy of bill of lading unless otherwise agreed. Request a commercial invoice with HS code 9030.89 for electrical measuring instruments. Ensure the device is labeled with CE, RoHS, and voltage input details as required by your country’s electrical safety regulations.
Perform a functional test on arrival using a known low-resistance standard or calibrated ground rod. Record readings across multiple frequencies and compare them to the stated accuracy. Check for consistent output current under load and verify that the display remains stable under ambient interference. Retain the original packaging and calibration documents for audit purposes. If the device fails initial tests, initiate a claim with the supplier before installation.
