We are involved in providing Digital Earth Tester. These products are made under the guidance of skillful professionals in compliance with worldwide industry standards. 

SIGMA Brand Electronic Digital Earth Resistance Tester 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 measurements of ground
resistivity. It can also be used for measurement of the other low regular and liquid resistance. This instrument finds wide application for testing earthing installations in power based industries, telecommunication networks and electrical traction systems, etc.

This is powered by rechargeable Ni-Cd cells. A LCD low battery indication appears when its battery goes down, which can be recharged by connecting mains AC supply through charging lead provided with the instrument.

Earth Electrode testing to investigate the effectiveness of the resistance to earth element of an earth installation (i.e. Resistance of earth connection) Soil resistance measurements of sites, giving data enabling the preferred positioning and depth of proposed electrode systems to be calculated. Measurement of low regular and liquid resistances.

The principle used in measuring the earth resistance is based on simple Ohms law, four Electrodes A B C D are buried in earth the
resistance of which is to be tested at a distance of 20 meters from each other as shown.
