Made with a self-shielding Annular d'Arsonval movement, this meter can be installed in steel panels without requiring recalibration. The Pivot and Jewel suspension is spring-loaded for shock protection. The case and cover feature the original Bakelite construction.

These meters require an external shunt (sold separately). The meters are calibrated for external 5-foot or 0.065Ω leads. Each 0.1Ω of resistance above or below that value changes the indication by 1% at full scale.

As a Simpson Authorized Modification and Repair Center, we keep the lead time short by stocking unfinished meters and completing final modifications and calibration in our laboratory. This meter, when produced this way, is not Underwriter Laboratories Recognized.

As an Authorized Simpson Modification Center, we can offer custom upgrades, such custom artworks and adding logos to dial artworks.
