Peace of mind before commissioning
This has become our go-to instrument during pre-commissioning tests. Used it for busbar joints, breaker contacts, and bonding checks. Never misses a fault. You can feel the engineering quality in your hands.
Compact size, industrial-grade output
Surprised by how compact it is for a 10A micro-ohmmeter. The data hold and auto-ranging features save time during busy inspection days. Great for verifying contact resistance in medium voltage systems.
Reliable, rugged, and spot-on accurate
We’ve used this unit to test grounding on multiple electrical panels and it delivers dead-accurate readings every time. Sturdy build, intuitive interface, and fast stabilization on measurements. Ideal for field crews.
