DIT-72 High Voltage Insulation Resistance Tester is a high performance high voltage insulation resistance tester of well research and development by our company. The tester has complete various insulation resistance index test functions, self-set test voltage function, and good anti-interference ability. It has obvious advantage in substation and other environments with strong induction and large distributed capacitance. The instrument equip with true-color touch screen, and all test data and battery power are displayed on the same screen which is clear and obvious. The combination of the rotary switch and the button makes the operation very simple. The user does not need to memorize the operation method, and the operation method will pop up by clicking the “HELP” button on the screen, effectively guiding the user to operate the instrument. The tester is suitable for insulation resistance testing of large-scale equipment such as electrical equipment and transmission lines in large-capacity, high-voltage, and strong-inductive environments. It is a commonly used and indispensable instrument in the departments of electric power, telecommunications, meteorology, computer rooms, oil fields,
