Electricity is a double-edged sword. It can bring us convenience by powering our homes,

or it could be a curse when it is unsafely handled. For example, the break down of electric

motors, cables and household appliances by high voltage or environmental factors such

as corrosion, sunlight, humidity and dust may affect insula�on or earth ground protec�on.

These events may result in economic and energy loss, human injury, or even lead to

catastrophes. UNI-T helps to minimize these risks by providing accurate and safe meters for

measuring insula�on, earth ground resistance, RCD, and more.
