This handheld milliohm meter helps you measure low resistance with confidence and speed. It delivers stable readings thanks to a four-terminal method and a rugged build that holds up in service work. Extech 380460 Precision Milliohm Meter (110V) suits technicians who need reliable results on joints, bonds, and windings. You get a compact tool that travels well and works hard.
Measurement clarity
Resolution down to 0.1 mΩ lets you see small changes that matter on safety grounds. The 4-wire Kelvin technique reduces the effect of lead resistance and contact pressure for cleaner results. Manual display zero helps you remove residual offsets before each run so your baseline is steady. Overrange indication tells you when a connection or component sits beyond the instrument’s reach, which prevents confusion.
Built for field reliability
A compact case with a protective cover withstands knocks, dust, and travel between sites. The layout is simple, so routine checks move quickly and training time stays short. The included Kelvin clip cables clamp securely and free your hands for notes and photos. You can carry it in a bag and be ready for call-outs without fuss.
Use it across maintenance, production checks, and quality assurance where low-ohm joints need proof. It supports quick passes on busbars, earth bonds, and harness connections with repeatable results. The design keeps the workflow light while the readings stay trustworthy. Your team gains a practical meter that does the job without getting in the way.
