Earth Resistance Meter MEG-432
MEG-432 is the ultimate tool for measuring the resistivity of soil and the resistance of the earth electrodes.
The wide range of the measurement combined with being easy to operate, made the device an ideal and reliable meter for wherever earth resistance testing is required.
The MEG-432 is widely used in different fields of industry Including: Power transmission lines developing, constructions, factory plants, etc. and also in educational institutes.
