5300 / st-5300b
با نمایشگر دیجیتال LCD بزرگ چراغدار و با نمایش ولتاژ باطری به طور همزمان
Electrical Digital Earth Resistance Tester is direct replacement of the conventional hand generator type tester. It is designed for measurement of the resistance of earthing used in the electrical equipment as well as for measurement of ground resistibility. It can be used for measurements of the other low regular and liquid resistances. It can also be used for measurement of voltage AC, voltage DC and resistance.
This instrument finds wide application for testing earthing installation in power based industries, telecommunication networks and electrical traction systems etc.
