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
