Introduction：          

High-End MultiFunctional Clamp Earth Resistance Tester, also known as clamp type earth resistance tester, single clamp earth resistance tester, loop resistance tester, lightning protection earth resistance tester, which is used for measurement of earth resistance, loop resistance, earth current and grounding fault judgment.

In the loop grounding system measurement, no need to disconnect the grounding down lead, and not request the auxiliary grounding pole, which is safe, fast and convenient to use.the clamp earth resistance tester is widely used in earth resistance and loop resistance measurement of electric power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment.The long clamp is particularly suitable for flat steel grounding site.

The tester can measure ground faults that cannot be measured by traditional methods, and can apply to the site which cannot be measured by traditional methods, because the clamp earth resistance tester is measuring the comprehensive value of the grounding body resistance and the grounding lead resistance.

 High-End MultiFunctional Clamp Earth Resistance Tester has multiple display mode combinations, you can choose resistance + current, resistance + time, current + time to display on the same screen, larger measurement range, 999 sets of stored data, lower power consumption, using large-capacity lithium batteries, the supporting monitoring software has functions such as online real-time monitoring, historical query, software alarm setting, historical data reading, saving, reporting and other functions.

Features:

1. A major breakthrough in earth resistance testing technology, non-contact type measurement is safe and fast. When measuring the grounding system with loop circuit, no need to disconnect the grounding down leads, and no need to add auxiliary stake, saving time and more effective. 

2. Measuring instrument manufacturing license: 2016E119-44 

3. The resistance and current are displayed on the same screen, the test results are clear and obvious. 

4. Have functions of audible and visible alarm, data memory, data hold. Clock function, display present test time. 

5. Equipped with USB interface, communication cable and software, the stored data can be uploaded to the computer for reading, saving and printing. 

6. Equipped with rechargeable lithium battery, convenient to use.
