Why choose the Megger MIT220?
✓ Cover everyday electrical testing
The MIT220 suits electrical contracting, site maintenance and service work. Its two insulation test settings provide options for checking domestic and industrial equipment.
Applications include fixed wiring, motors, generators, transformers, switchgear, electrical panels, domestic appliances and power tools. This makes it a useful instrument for teams working across different types of equipment.
✓ Keep continuity checks practical
Continuity testing starts automatically when the test leads are connected to the circuit. This leaves both hands available to position the probes.
Lead null compensates for resistance in standard, extended or fused test leads, helping you account for the leads in your measurement. The 2Ω buzzer threshold provides an audible indication during continuity checks.
✓ See readings and voltage warnings clearly
The combined digital display and analogue arc give you two ways to view results. Battery condition indication helps you monitor the instrument’s power supply.
The voltage display activates when AC or DC voltage above 25V is detected. Testing is inhibited above 50V on both insulation and continuity ranges. These features provide warnings and protection against accidental connection to a live circuit.
