Digital Micro Ohmmeter for Low Resistance Measurement (0.001 mΩ to 300 kΩ)
A high-precision digital micro ohmmeter designed for accurate low-resistance measurement using four-wire testing. Ideal for electrical maintenance, grounding checks, contact resistance testing, and industrial diagnostics.
This professional digital micro ohmmeter is designed for precise measurement of very low resistance values in electrical and industrial applications. Using microprocessor control and four-wire (Kelvin) measurement technology, it delivers safe, stable, and highly accurate resistance readings across a wide measurement range.
The instrument is suitable for testing cable resistance, contact resistance of switches, relays, connectors, grounding conductors, and metal connections. It is commonly used in electrical distribution rooms, switchgear panels, transformers, coils, grounding systems, and equipment contact points where low-value resistance measurement is critical for performance and safety.
Automatic and manual range selection allows flexible operation across different measurement tasks, while line resistance calibration improves accuracy in field conditions. A clear digital display presents readings in real time, and onboard data storage supports documentation and troubleshooting.
USB connectivity enables data transfer to a computer for analysis and reporting, while the built-in rechargeable lithium battery provides portable operation for site work and maintenance inspections. This low resistance tester is an essential tool for electricians, technicians, and engineers working in power, industrial, and electrical infrastructure environments.
