Vacuum Interrupters Launches LRTS10 Battery-Powered Micro-Ohmmeter
Denton, Texas – September 19, 2026 -- Vacuum Interrupters Inc. has introduced the LRTS10, the first digital micro-ohmmeter built on the Milwaukee M18 REDLITHIUM battery platform, targeting technicians who service medium-voltage switchgear, busbar joints, and cable terminations.
Battery swap replaces downtime for recharging cycles
Rather than pausing to recharge a proprietary battery, crews can swap in a fresh Milwaukee M18 pack and resume testing immediately. The LRTS10 is compatible with all M18 batteries, allowing utilities and contractors already using Milwaukee tools to power the test set with packs already stocked on service trucks.
Each unit ships with an M18 XC5.0 battery rated for over 1,100 tests
The standard package includes test leads, a cable bag, a charger, and an M18 XC5.0 battery. Vacuum Interrupters states the battery can deliver more than 1,100 tests before requiring a recharge or swap.
