MI 2126 Earth 2/3


The MI 2126 Earth 2/3 is a high quality, professional grade test instrument for performing three-wire earth resistance measurements in accordance with European standard EN 61557-5, on which the estimation of earthing quality is based. The equipment was designed and produced according to many years of experience of producing and dealing with earth resistance and electric installation test equipment.


MEASURING FUNCTIONS:


• Earth resistance, 3-wire method. KEY FEATURES:


• Earth resistance measurement: in- strument performs standard 3-wire earth resistance tests with two earth- ing rods.


• Easy to use: only 3 buttons control all the operations of the test instrument and instruction manual explains various earth resistance measuring methods.


• Portable: the MI 2126 is light and bat- tery operated instrument and can be easily placed with other test instru- ments for moving between tested items.


• Reliable: reliable results even in the presence of stray currents.


• Repeatability: outstanding repeatabil- ity of test results especially in the case of high test probe resistance of various earthing structures (e.g. asphalt, sand, and stone).


APPLICATION:


• 3-wire earth resistance testing; • Testing single rod and multiple spiked earthing networks.
