Digital
Earth Resistance Testers are useful for measurements of earth resistances, soil
resistances, earth continuity, neutral and earth loop resistances,
resistances of various components, etc.
Useful for
railways, defence, electricity boards, power generating plants,
geological surveyors, industries, telecommunication networks, electrical
traction systems, etc.
Four terminal
measurement system avoids errors due to spike and testing wires
resistances.
Direct reading of
resistances on 3½ digit, 7 segment type of LCD display of 12.5mm height
with decimal point and over-range indications.
