Overview

ETCR3500 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, electromechanical installation and maintenance, and power supply departments of industrial and mining enterprises.

The test timer of the instrument automatically records the test time and stores the test results with date and time. The touch screen can easily check the recorded historical data. The completely isolated USB interface and Bluetooth communication can safely upload the test data to the PC or mobile phone for users to analyze data. The instrument provide with the test lines of double-layer insulation and shielding layer, and the high-voltage rod is equipped with replaceable alligator clips and hooks, which can be adapted to various test sites. The instrument adopt with solid double-layer shell structure, and the protection level of the case is IP65, which can prevent the intrusion of moisture and dust during transportation and storage, and prevent impact and effectively protect the instrument.
