Megger MIT320-EN Digital Insulation Tester
The Megger MIT320-EN Digital Insulation Tester combines insulation, continuity, resistance and voltage measurement in one portable instrument. It provides 250 V, 500 V and 1000 V insulation test settings with an insulation resistance range extending to 999 MΩ. A digital and analogue style LCD display gives a clear view of readings while retaining an analogue response for changing values.
For day-to-day electrical work, the tester includes continuity measurement to 100 Ω, lead null to 9 Ω and an adjustable continuity buzzer from 1 Ω to 20 Ω. Its backlit display helps when working in darker areas, while the switched test probe supports one-handed operation. The Megger MIT320-EN Digital Insulation Tester also measures voltage up to 600 V AC/DC and resistance from 10 Ω to 1 MΩ.
Safety features include live-voltage warning, safety interlock, safe contact detection and a safety lockout that prevents testing when circuit voltage is above 50 V. The rubber-armoured design is intended to withstand demanding site use, and the display cover protects the screen when the instrument is stored. With IP54 weatherproofing and battery operation, the Megger MIT320-EN Digital Insulation Tester is suited to testing, maintenance and fault-finding tasks in a range of working environments.
Key Benefits
- Three insulation test voltages provide flexibility for different insulation checks.
- A 999 MΩ insulation test range supports testing across a broad resistance range.
- The backlit display improves reading visibility when working in darker areas.
- An adjustable continuity buzzer supports quick go or no-go continuity checks.
- Lead null to 9 Ω helps compensate for test lead resistance during continuity work.
- The switched test probe allows insulation tests to be started from the probe for easier one-handed use.
- Safety interlocks, live-voltage detection and lockout functions help prevent unsafe testing on live circuits.
- The rubber-armoured body and protective display cover help the instrument withstand regular site handling.
- Automatic continuity and buzzer operation on connection can reduce the number of manual steps during testing.
- Colour-coded ranges and simple controls help make test selection clear and support faster fault location.
Common Applications
Megger MIT320-EN Digital Insulation Tester is suitable for a range of testing, maintenance and inspection tasks, including:
- Electrical maintenance checks
- Wiring insulation testing
- Circuit continuity checks
- Resistance measurement and fault finding
- Control panel testing
- Assembly plant testing
- Automotive engineering checks
- DIY electrical repair checks
Why Choose This Model?
The MIT320 adds a backlit display, adjustable continuity alarm, 10 Ω to 1 MΩ resistance measurement, insulation limit alarm and switched test probe compared with the more basic functions shown for the MIT300 and MIT310. The MIT330 adds 1000-result storage and downloading, while the MIT320 provides the listed testing functions without those recording features.
