The Sonel MMR-650 Low Resistance Ohmmeter is designed for precision verification of very low resistance values in switchgear, busbars, motors, and bonding connections, giving maintenance engineers a reliable way to identify contact degradation and ensure electrical integrity.
Optimised for field use, the Sonel MMR-650 combines four-wire Kelvin measurement, selectable high test currents, and intuitive on-screen guidance. Whether you need to rent or hire a micro-ohmmeter for commissioning, routine inspections, or troubleshooting, the MMR-650 delivers stable readings even in demanding industrial environments.
Key Features:
- High-current Kelvin method: Four-terminal configuration minimises lead resistance for accurate low-ohm results.
- Wide resistance range: Covers micro-ohm to low-ohm measurements, ideal for busbar joints, transformer windings, and bonding checks.
- Large, backlit colour display: Clear numeric and graphical data presentation improves readability in poorly lit switchrooms.
- Internal memory & PC connectivity: Store test results on board and transfer via USB for detailed reporting and compliance records.
- Rugged field housing: Durable IP-rated enclosure withstands industrial environments and frequent transport.
