Megger MIT320 Insulation and Continuity Tester

Megger MIT320 Insulation and Continuity Tester

The Megger MIT320 is the second-highest specification model available in Megger's MIT300 series and is the upgraded version of the MIT300, MIT310 and MIT310.

A powerful, handheld and easy to use insulation and continuity tester, the Megger MIT320 is made tough for use on site, with rubber armoured casing and rigid display cover which locks down to protect the tester when not in use.

Megger's MIT320 can perform insulation tests with test voltages of 250, 500 and 1000V with maximum testing range of up to 999MΩ. Testing procedures can be activated directly from the tester, or alternatively you can use the switched probe supplied with the MIT320 to activate the tests remotely. For added convenience, continuity testing will automatically activate when connected to the circuit.

The main exclusive additions which are added to this unit compared to other MIT300 units include an insulation limit alarm (from 0.01MΩ to 999MΩ), adjustable continuity buzzer (1 to 20Ω) with the ability to disable and the ability to carry out resistance measurements from 10Ω to 1MΩ.

Megger's MIT300 series is built with safety in mind - this insulation tester includes a number of protective safety measures including a Safety Interlock which will prevent unsafe test lead connection, safe contact detectors which will protect the tester even if the MIT is connected to live circuits when on continuity setting and even a safety lockout which will prevent the test from operating if voltage is above 50V.
