Key choices are:
• Analogue or digital?
• 500V only or 250 and 1000V as well?
• Do you need to monitor the test voltage to ensure it’s really at least 500V?
• Do you need to store test results for later recall?
• Do you need Polarisation Index (PI) or Dielectric Absorption Ratio (DAR) for more accurate measurement?
Unfused and fused leads fit all Martindale Insulation Testers
A choice of 7 insulation testers from low cost, value-for-money, to cutting-edge technology.
Recommended for use on mains circuits
