Megger enhances insulation testers

-December 26, 2016

Megger’s MIT480/2 series of insulation and continuity testers is not only faster, but provides gated access to 500 V to minimize the risk of accidental damage to equipment under test. Intended for the telecommunication and cable testing markets, the handheld units offer quick single-range continuity testing that is fully automatic from 0.01 Ω to 1 MΩ. They also furnish a user-selectable test current of 20 mA or 200 mA.

The series comprises two models—the MIT481/2 and MIT485/2—both of which employ a three-wire connection for A, B, and E (tip, ring, and ground), eliminating the need to connect and disconnect leads to carry out the full range of tests on a cable pair. The testers have a CAT IV 600 V safety rating and perform insulation testing up to 500 V and 100 GΩ. Their feedback-controlled insulation test voltage is accurate to +2%.

The MIT481/2 offers four fixed test voltages of 50 V, 100 V, 250 V, and 500 V, plus onboard storage of test results, while the MIT485/2 adds a variable test-voltage function and Bluetooth downloading capability. Each instrument comes in a rugged housing with shock-absorbing rubber overmolding.
