Megger MJ15 Analogue Insulation Tester 5 kV
Description
The Megger MJ15 is a compact 5 kV insulation tester. It is very simple to use and provides a quick and accurate reading of insulation resistance. The instrument uses an analogue display with a maximum reading of 20 GΩ. The MJ15 has an additional hand-cranked generator.
Features
- Large, single scale analog display
- Auto voltage measurement function indicates conductor and auto discharge potential
- Supplied with optional locking test button
- Safety recessed terminals and long connectors
- Four output test voltages
- Simple to use
- CE marked
- Dual power supply option on MJ15
- Unique scale overlay for pass/fail bands
- Resilient mounted analogue scale for robustness
- Single scale for insulation values to avoid operator error
- Light weight and rugged
- Range down to 100kΩ ideal for go/no go testing
