TEGAM Inc. R1L-E2A Rugged, Portable, Intrinsically Safe Microohm and Bond Meter, 10 µO to 20 O, 0.1%, 3.5 Digit includes standard "HTP-101A" probes
The Model R1L-E2A is the only electrical bonding meter certified to ATEX, UL and CSA intrinsically safe standards. It is used on the Lockheed F-35 Joint Strike Fighter and C-130 Hercules airframes as well as the Sikorsky S-70, S-92 and Seahawk helicopters to test electrical bonds on antenna installations, electrical safety grounds and lighting protection systems.
A rugged heavy-duty plastic case is provided to contain and protect the instrument. When closed, a gasket seals the lid to keep out water and dirt when the Model R1L-E2A is transported through rain or other environmentally hostile conditions. When the lid is open, a second gasket provides a seal for the front panel, and all panel openings are sealed to prevent water entry, as is the removable battery cover.
Two different styles of 4 wire Kelvin probes are available to adapt to the physical conditions. Both the large HTP-101A pistol grip probes and the smaller SKP-8 hand probes are designed with static dissipating properties and are an integral part of the intrinsic safety system. The SKP-8 probes have a choice of replaceable tips to further accommodate the work requirements.
The Model R1L-E2A is battery powered by three internal heavy-duty alkaline "D" cells. Front panel controls include a POWER ON-OFF switch and a rotary range selector switch. Five resistance ranges are provided from 2 mΩ to 20 Ω.
