Yokins 4 Terminal Type Earth Tester, 3/30/300/3000 ohms

Key Features

• Yokins Hand driven generator type Earth Tester is a compact, portable self-contained Instrument which is used to measure the earth resistance if earth is used in power circuit, telecommunications, Railway Electrification, Domestic and Industrial electrical installations, Lighting Protection Installation and various other Electrical systems. The tester performs equally well in Terrain where the conductivity of the soil is low, e.g., in mountainous areas and in places where powerful stray earth current exist..

• The four terminal instrument is specially designed for making straight forward and approximate soil investigation of the kind needed in agricultural, geological research and in the planning of large civil engineering projects such as tunnels, Drainage, Sewerage schemes, Tube- Railways etc..

• Measuring accuracy of the instrument is not effected by stray alternating or back e.m.f of earth electrolyte. The instrument can also be used for measuring non-inductive or non-capacitive resistance..

• Silent generator: The AC Magnet hand generator drive is extremely smooth and silent..

• Accurate reliable and Quick response For measurement of earth Resistance..

• The quick response saves the time and extend the life of the generator..

• Limits of error: The earth resistance measurement is accurate to within( /-)5% of the indicated value over the effective range and within ( /-)10% of the indicated value at the scale mark for the rest of the ranges in conformity with I.S.9223..
