The intrinsically safe one.
Safe for use on fuelled aircraft, the ExLRT® is designed with MROs in mind. It’s the modern alternative to the 'yellow box' LRT and is a specified tool in several Aircraft Maintenance Manuals (part number XLR-9703-01).
The ultimate tool to carry out prescribed loop resistance testing on aircraft during maintenance, the ExLRT is certified by all global standards as safe for use in high-risk flammable zones. It’s small and light enough to be used by a single operator, and automatically records all test data, eliminating the need for paper records.
