Portable micro-ohm meter for accurate low-resistance measurement in transformers, switchgear, and electrical connections.
This high-precision DC resistance tester is designed for accurate measurement of low resistance values in electrical equipment and conductive connections. Utilising a 4-wire (Kelvin) measurement method, it minimises lead and contact resistance effects, enabling reliable micro-ohm level readings.
With high test current capability (up to 20A), the device is suitable for testing transformers, circuit breakers, busbars, cables, and bonding connections where low resistance measurement is critical for performance and safety verification.
The digital display provides clear readout of measurement values, while the portable design allows for both field and workshop use. The unit is commonly used in commissioning, maintenance, and inspection of electrical systems.
This tester is well suited for electrical contractors, maintenance technicians, and engineers requiring accurate resistance measurement for diagnostics and verification tasks.
