Premium Vici VC4105A Ground Resistance Tester (Earth Tester) in Malaysia | Authorized Solutions by MTM Precision

Elevating Electrical Grounding Safety, Lightning Protection System Verification, and Industrial Infrastructure Reliability Across Malaysian Enterprise Infrastructure.

High-Precision Earth & Ground Resistance Testing for Modern Industry

In today's fast-evolving industrial, commercial, and utility sectors, maintaining a robust electrical grounding system is paramount. Proper earth grounding protects equipment from lightning strikes, prevents electrostatic buildup, dissipates fault currents safely into the ground, and ensures operator protection across power facilities, telecommunications towers,and manufacturing plants.

Shenzhen Vicimeter Technology Co., Ltd. (globally recognized under the Vici brand) engineered the Vici VC4105A Ground Resistance Tester (Digital Earth Tester) to deliver accurate, reliable ground grid diagnostics. Featuring dual 2-wire and 3-wire testing capabilities, high withstand voltage insulation, and comprehensive overload protection, the VC4105A provides field engineers and maintenance contractors with factory-backed equipment built for demanding outdoor and site conditions. Distributed in Malaysia by MTM Precision Sdn. Bhd., this instrument helps local enterprises comply with strict electrical safety codes and Suruhanjaya Tenaga regulatory standards.

Detailed Technical Feature Breakdown

820Hz High-Frequency Test Current Architecture

Standard power mains operate at 50Hz in Malaysia. The VC4105A uses a targeted 820Hz test frequency at a low 3mA test current to effectively isolate and eliminate stray ground currents and power line harmonics, ensuring true ground resistance readings.
Dual 2-Wire & 3-Wire Testing Versatility

Offers standard 3-wire testing (using auxiliary earth spikes P and C) for accurate precision measurements on primary ground pits, as well as a simplified 2-wire method for quick checks in urban locations where driving ground spikes is impractical.
High Dielectric Strength (3700V AC Withstand Voltage)

Engineered with heavy-duty insulation capable of withstanding up to 3700V AC for 1 minute between the internal measurement circuitry and the outer body cover, ensuring maximum user protection against unexpected potential rises.
Press-and-Lock Continuous Test Function

Features a dedicated locking test button. Technicians can press and turn the button to lock the test current ON continuously, leaving both hands free to adjust connections or record readings across multi-point ground arrays.
Advanced Environmental Durability

Operates reliably across wide temperature ranges (-10°C to 50°C) and relative humidity up to 80%, built to withstand Malaysia's demanding outdoor jobsite environments.
