(R1L-E2A) Intrinsically Safe Milli-Ohmmeter and Bond Meter, 10 µΩ to 20 Ω, with HTP-101A probes



Product Description

Intrinsically Safe Milli-Ohmmeter and Bond Meter

with HTP-101A Kelvin Probes

10 µΩ to 20 Ω

The Model R1L-E2A is the only electrical bonding meter and milli-ohmmeter 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 Kelvin 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 Kelvin 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.
