Elecgene handheld micro-ohmmeters are designed for circuit breaker contacts, switchgear main circuits, busbar joints, disconnectors, grounding connections, cable joints, fuses, welded connections and other low-resistance conductive paths.
Available 100A and 200A models combine selectable DC test current, 0.1 μΩ resolution, rechargeable battery operation and a lightweight handheld design for factory, substation and industrial field testing.

30A-220A current output for different use
Elecgene handheld micro-ohmmeters provide high test currents for measuring low-resistance electrical connections. The HLR-100 offers selectable 30A, 50A, 80A and 100A outputs, while the HLR-200 supports outputs up to 200A, with an optional 220A configuration.
Both HLR-100 and HLR-200 provide 0.1 μΩ resolution for low-resistance measurement, supporting detailed evaluation of electrical contacts and connections.
The four-wire Kelvin connection separates the current and voltage measurement paths, helping reduce the influence of test-lead resistance when measuring very low resistance values.
The HLR series combines a handheld form factor with a built-in lithium battery, allowing low-resistance measurements to be carried out in field locations without relying on a fixed mains power supply.
Test results can be stored and exported for record keeping. The HLR-100 also supports an external printer and USB storage, making it easier to produce and retain test records during field work.
A micro-ohmmeter is a low-resistance measuring instrument designed to measure resistance in the micro-ohm and low milliohm ranges. High-current models are commonly used for circuit breaker contacts, busbars and other power connections.
Two leads supply the test current and two separate leads measure the voltage drop. This Kelvin connection reduces the influence of test lead resistance on the result.
Micro-ohmmeters are commonly used to measure low resistance in circuit breaker contacts, switch contacts, busbar joints, disconnectors, cable connections, fuses, grounding connections and other high-current conductive paths. The appropriate test current and procedure depend on the equipment under test.
Consider the required test current, resistance range, measurement resolution, test duration, power supply and portability. For field circuit breaker and connection testing, a battery-powered instrument with high-current output and four-wire Kelvin measurement can provide a practical combination of low-resistance measurement capability and portability.
