The Megger MIT300 series insulation resistance tester measures insulation resistance, voltage, and continuity in electrical installations, building maintenance, and electrical testing. The average-sensing meter provides accurate readings when measuring linear loads, where the current or voltage has a sinusoidal waveform. The dual LCD screen indicates test results either digitally or with an analog arc function to replicate the response of analog meters.
