About AEMC INSTRUMENTS

AEMC Instruments, founded in France in 1893 and now headquartered in Dover, New Hampshire, USA, is a manufacturer of electrical test and measurement instruments. The company’s product line focuses on portable, field-ready equipment for electrical testing, power quality analysis, and ground resistance measurement. 3G Electric supplies a range of AEMC Instruments products, including micro-ohmmeters, megohmmeters, earth ground resistance testers, and associated accessories such as Kelvin probes. These instruments are designed for use in industrial, utility, and commercial settings where accurate measurement of insulation resistance, low-resistance connections, and grounding systems is required. AEMC Instruments’ offerings are characterized by rugged construction, with many models carrying IP ratings from IP51 to IP65, indicating protection against dust and water ingress suitable for harsh environments. Safety ratings include CAT III and CAT IV, up to 1000 V, aligning with international standards for overvoltage protection. The product range covers measurement spans from micro-ohms (e.g., 2 µΩ to 50 µΩ on the Model 6240) to tera-ohms (e.g., 10 kΩ to 30 TΩ on the Model 6555), with test voltages up to 5,000 V DC. Earth ground testers measure resistance from 0.01 Ω to 100 kΩ, with test currents typically ≤250 mA. Many units feature digital displays, USB connectivity for data transfer, and compliance with CAT safety ratings. 3G Electric supports these instruments by offering them as part of a broader catalog of industrial test equipment, with logistics for global shipment. The selection includes kits with extended test leads (e.g., 300 ft or 500 ft) for field applications. For plant engineers and maintenance managers, AEMC Instruments provides tools for preventive maintenance, fault diagnosis, and compliance testing of electrical systems. The instruments are suited for applications such as motor insulation testing, transformer winding resistance measurement, and grounding system verification. No specific certifications or awards are claimed beyond the inherent product specifications and safety ratings listed.
