The Martindale IN2101 insulation tester is the ideal low cost solution.
Testing at 500V, it's suitable for domestic installers, as well as domestic appliance repair companies.
It features a large backlit LCD display with analogue arc, continuity buzzer and auto hold. An automatic zero adjust removes the resistance of the leads and the test button can be set to either latching, to give a permanent output, or 'press to test'.
The IN2101 is fully compliant with all UK and International standards, including the 17th Edition, and is supplied with unfused test leads with croc clips, batteries, instruction manual and a soft carry case.
