Insulation Resistance Tester

Digital High Voltage Insulation Tester


The DT-6605 insulation resistance tester offers digital insulation testing up to 5kV, making it ideal for testing a wide range of high voltage equipment including switchgear, motors, generators and cables. These can conduct the entire range of test voltages with a best in class, 1-year warranty, confirmation to EN:61010-1 and CAT IV600V safety rating.

These are perfect tools for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.

Note:This monitor is used to check whether electric charge stored in the equipment under test is discharged or not. Measured voltage value displayed on the LCD is a reference value. Please be noted that the indicated value, when external AC or DC  Voltage is applied to the instrument is not the correct value , is display “>30V”.
