High Voltage Insulation Tester

The HM2010 Insulation Resistance Tester, also known as a digital megohmmeter or electrical resistance tester, consists of a main unit and test leads. The main unit features a dedicated toolbox-style design. Made from polypropylene plastic with the addition of new composite fillers, it is formed through a single-shot injection molding process. This results in a material with low density and superior strength, rigidity, hardness, wear resistance, heat resistance, and insulation properties. The housing can withstand approximately 100 kg of pressure, ensuring high precision, stability, and reliability during testing in various environments. The main unit features an extra-large LCD display with backlighting and an analog bar graph, providing clear and intuitive readings.
