MEGGER MIT320 Insulation Tester | 1000V Digital/Analogue Megohmmeter for Electrical Maintenance

Reliable Insulation & Continuity Testing with IP54 Protection in Sri Lanka

The MEGGER MIT320 is a rugged, professional digital insulation tester combining digital and analogue displays for precise insulation resistance measurement up to 1000V. Featuring selectable test voltages of 250V, 500V, and 1000V DC with 1.5mA short circuit current, it's ideal for electricians and maintenance professionals testing motors, cables, switchgear, and electrical installations across Sri Lanka. With IP54 weatherproofing, CAT III 600V safety, live circuit detection (>25V warning), and automatic discharge, the MIT320 ensures safe, reliable field performance in demanding conditions.

Designed for tough site use, the MEGGER MIT320 offers hands-free neck strap operation, switched test probe, and rubber armoured case with protective cover. Its unique digital/analogue display provides clear 20mm high characters plus analogue arc for trend monitoring, while backlit display and colour-coded ranges simplify operation. Battery efficient with 5000+ tests per set of AA batteries, the MIT320 meets BS7671 and IEC 61557 standards for comprehensive insulation and 205mA continuity testing with adjustable buzzer threshold.

Key Features of the MEGGER MIT320 Insulation Tester

250V-1000V Insulation Test Voltages: Selectable 250V, 500V, 1000V DC test voltages with 1.5mA short circuit current and 1mA test current at BS7671 pass values for accurate insulation diagnostics up to 999 MΩ.
Digital/Analogue Dual Display: Unique 20mm high digital characters + analogue arc provides both precise readings and trend monitoring with true analogue response for professional insulation assessment.
High-Power Continuity Testing: 205mA nominal test current from 0.01Ω to 99.9Ω with adjustable buzzer threshold (1-20Ω) and 20ms response time for rapid circuit continuity verification.
Intelligent Safety System: Live voltage warning (>25V), safety interlock prevents testing above 50V, safe continuity detection, and automatic discharge protect users and equipment during field testing.
IP54 Weatherproof & Rugged Design: Rubber armoured case with fold-away protective cover, neck strap for hands-free use, and IP54 rating withstands site conditions and 1m drops onto concrete.
Backlit Display & Switched Probe: Backlit display for low-light reading plus SP4F switched test probe enables remote one-hand insulation testing without returning to the instrument.
600V AC/DC Voltage Detection: Default voltmeter function automatically detects and displays 0-600V AC/DC (50/60Hz) with safety lockout above 50V, preventing unsafe insulation tests.
Ultra-Long Battery Life: 8 x AA alkaline batteries deliver 5000+ consecutive tests (5 seconds each) with constant battery bar graph monitoring and auto power down after 10 minutes.
International Safety Compliance: Meets IEC 61010-1 CAT III 600V, IEC 61557, BS7671 requirements with 500mA/600V fuses and EMC compliance for professional electrical certification.
