Overview
Enviro Test Construct resistance moisture meter is an advanced tool designed for testing insulation resistance parameters in high-capacity, high-voltage environments, including substations and transmission lines. Featuring a true color touch screen, it consolidates all test data and battery status, ensuring user-friendly operation. With a quick discharge function and automatic voltage monitoring, it prioritizes safety, halting testing if voltages exceed 36V. Equipped with a rechargeable lithium battery pack, it records test duration, stores results, and offers easy historical data access. It’s robust build with an IP65 rating shields against moisture, dust, and collisions during transportation. Offering various tests, including insulation resistance, polarization index, absorption ratio, and more, it serves as a crucial instrument in multiple industries such as power, telecommunications, and industrial enterprises’ power supply departments.
