ST2241-3min-V1.0_20251010_13593970

2.1 Basic Functions and Basis Standards: ST2241 Grounding resistance. The soil resistivity tester is a comprehensive testing instrument for on-site measurement of grounding resistance, soil resistivity, grounding voltage and AC voltage in grounding system investigation and acceptance. It complies with the national standard GB/T 179491-2000 "Guidelines for Measurement of Soil Resistivity, Grounding Impedance and Ground Potential of Grounding Systems - Part 1: Conventional Measurement".

2.2 Instrument set composition: ST2241 grounding resistance. The soil resistivity tester is composed of a main unit, computer monitoring software, soil stratification analysis software, test leads, auxiliary grounding rods, communication wires, etc.

2.3 Advantages and Characteristics:

The tester is designed in accordance with national standards and industry norms, leading in China. It complies with the national standard GB/T 179491-2000 "Guidelines for Measurement of Soil Resistivity, Grounding Impedance and Ground Potential of Grounding Systems - Part 1: Routine Measurement".2) Equipped with intelligent computer software, it can save, query, statistically analyze data and print reports. Among them, the soil resistivity stratified analysis software is the only one in China and leads the industry.

3) USB communication interface, which is versatile, convenient and fast. These ports are superior to RS232 or 485 methods and are difficult for ordinary computers to be equipped with!

4) It can be operated independently without a computer, featuring miniaturization and integrated manual and automatic operation. The operation is simple and convenient, and the performance is stable. All parameter Settings and function conversions are input through the digital keyboard. Avoid the drawbacks of traditional mechanical switch types such as unstable performance and limited lifespan.

7) Expandable functions: In addition to being used as a soil resistivity tester, the resistivity tester can also be equipped with a four-probe test bench and the probe can be expanded into an AC four-probe tester.

2.4 Scope of Application: It is widely used in the measurement of grounding resistance, soil resistivity, grounding voltage and AC voltage in power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment, etc.
