Product introduction
SJC-7 Digital Display Insulator Tester is mainly used to measure the insulation resistance of insulators in power system to ensure the reliable and safe operation of transmission lines. It can also be used as a general megger to measure the insulation strength of other high-voltage electrical equipment. It is applicable to all departments with power transmission lines, such as electric power, agricultural power and water conservancy, as well as industrial and mining enterprises and scientific research institutions that produce and use various high-voltage electrical equipment.

Product advantages
● This instrument is small in size and light in weight.
● High voltage electricity is formed by electronic circuits and powered by batteries.
● Digital display, accurate, stable and intuitive measurement.

Features
1. Small size and light weight.
2. The high voltage output of the instrument is formed by electronic circuit and powered by battery. When measuring, only one person needs to operate with one hand, which is simple and convenient, and there is no need to shake the generator like a megger.
3. Digital display, accurate, stable and intuitive measurement.
