MI2124It is a multifunctional grounding resistance tester that includes three measurement methods:

1Standard four line methodThe traditional method of using ground stakes to measure grounding resistance can be used, and the two, three, and four line methods can be used to calculate soil resistivity.

2Double clamp method:No need for piling, quick measurement.

3: Select electrode methodFor parallel grounding wires, the grounding resistance of the grounding wire can be accurately measured without disconnecting it.

MI2124 Precision Grounding Resistance Tester Function:

-2, 3, and 4 pole method for testing grounding resistance

-Select electrode method to test grounding resistance

-Double clamp method for testing grounding resistance

-Soil resistivity testing function

-Current (effective value) testing function

Characteristics and advantages of MI2124 precision grounding resistance tester:

-The instrument has strong anti-interference performance and digital signal processing capability. When encountering interference and unstable big data, the digital filter can be turned on

-The input impedance is high. For areas such as concrete floors where ground stakes cannot be driven, steel drills can be directly placed on the ground and then replaced with water or a large wet towel can be placed

-Over limit or incorrect test condition alarm

-1000 test storage and analysis software

-Rechargeable battery power supply, automatic shutdown function
