The Martindale IN2103 is the top of the range insulation tester, and ideal for industrial use, as well as by users involved with the repair and reconditioning of motors.
Two key features of this professional tester include polarisation index (PI) and dielectric absorption ratio measurements (DAR). These sophisticated tests, introduced by Martindale for the first time in a handheld instrument, allow for more accurate measurement of insulation values.
In addition the IN2103 displays the test voltage on the large backlit LCD display, features an analogue arc, continuity buzzer and continuity buzzer, auto hold and an automatic zero adjust which removes the resistance of the leads. The test button can also be set to either latching, to give a permanent output, or 'press to test'.
The IN2103 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.
