Megger MIT400/2 Insulation Tester

Megger MIT400/2 Insulation Tester — Rugged CAT IV Insulation & Continuity

The Megger MIT400/2 is a rugged, professional insulation and continuity tester built for electricians and industrial maintenance teams. Offering 250 V, 500 V and 1000 V insulation testing to 200 GΩ, fast continuity and true-RMS voltage measurement, it delivers accurate results to EN 61557 in a tough CAT IV 600 V, IP54 handheld — the entry model of the popular MIT400/2 range.

Who the Megger MIT400/2 is for

The Megger MIT400/2 suits electricians, panel builders and maintenance technicians whose test sheets only ask for 250 V, 500 V or 1000 V insulation readings plus low-ohm continuity, and who have no need for stored results or a polarisation index. It is the base model of the MIT400/2 series, so it shares the over-moulded IP54 case and CAT IV 600 V rating of the higher models while keeping the controls simple.

Points from Megger’s MIT400/2 datasheet (V08) that matter on site:

• Feedback control holds the test voltage within −0% / +2% of nominal, so sensitive circuits are not stressed by overshoot
• Test inhibit blocks an insulation test when more than a user-set 25, 30, 50, 75 or 100 V is present (50 V by default)
• Lead null removes up to 9 Ω of lead resistance from continuity results
• An analogue arc beside the dual digital readout shows charge and discharge behaviour that a number alone hides
• Short-circuit charging current of 2 mA, in line with EN 61557-2

Megger MIT400/2 Key Features

What the Megger MIT400/2 does in daily testing:

• Insulation testing — 250 V, 500 V and 1000 V DC test voltages with 50, 100 and 200 GΩ ranges; ±2% ±2 digits, plus 0.2% per GΩ at 1000 V.
• Continuity testing — 200 mA test current on a single auto-ranging 0.01 Ω to 1 MΩ range, with a buzzer limit adjustable from 1 to 200 Ω.
• True-RMS voltage — DC 0–600 V and true-RMS AC 10 mV–600 V (15–400 Hz).
• CAT IV 600 V safety — rated for demanding industrial environments.
• Rugged & weatherproof — IP54 dust- and splash-protected case.
• Long battery life — about 3000 insulation tests (5 s on, 55 s off at 1000 V into 1 MΩ) from 6 × AA cells; NiMH cells also fit.
• Compact & portable — 228 × 108 × 63 mm and 600 g; 1.75 kg packed in the hard case.

Megger MIT400/2 Applications

The MIT400/2 is ideal for electricians and industrial maintenance teams performing insulation-resistance and continuity testing — on cables, motors, switchgear and installations — where a rugged, accurate CAT IV tester is required.

Megger MIT400/2 FAQ

Short answers for MIT400/2 buyers:

• Can the MIT400/2 test at 50 V or 100 V? No. Its fixed ranges are 250, 500 and 1000 V; the 50 V and 100 V ranges start with the MIT410/2.
• Does the MIT400/2 work out PI or DAR? No. Polarisation index, dielectric absorption ratio and timed tests come with the MIT410/2 and the models above it.
• Can it store or download results? No. Storage of more than 1000 results arrives with the MIT420/2, and Bluetooth download with the MIT430/2.
• Will it run on rechargeable cells? Yes. Six 1.2 V NiMH AA cells can replace the alkaline set; the mains charger kit is offered only for the MIT430/2.

Why buy the Megger MIT400/2 from MME

MME (MOHAMMAD MAHDI Electronics Trading LLC) can help you decide whether the three fixed voltages of the MIT400/2 are enough, or whether a model with 50/100 V, PI/DAR or result storage suits your test sheets better. Message us on WhatsApp for a quotation.
