Product Introduction

ETCR EM3250 Pylon Earth Resistance Tester, also known as four-clamp pylon earth resistance tester and pylon earth resistance tester, which is used for measurement of pylon earth resistance, soil resistivity, earth voltage, earth current and AC current. Transmission line pole pylon usually have 2 or 4 down leads. When using grounding pile method or clamp method to measure the earth resistance, need to disconnect the connection between the down lead and the grounding pole, and the measurement work is cumbersome and require large amount of work. This tester adopt with 4-clamp method to measure the earth resistance value of the pylon, not request to unbuckle the measurement. Wireless communication is used between 4 current clamp and the host, and the on-site measurement is fast and safe, which greatly reduce the work intensity of the operator and improve work efficiency.

ETCR EM3250 Pylon Earth Resistance Tester can also use the two-three-four-wire method to measure earth resistance, soil resistivity, AC current and earth voltage. The tester has unique anti-interference ability and environmental adaptability, and good consistency in repeated test to ensure high precision, high stability and high reliability of long-term measurement. The 4 current clamp of the tester can be used independently as clamp type current tester to measure AC current.

ETCR EM3250 Pylon Earth Resistance Tester consist of host, 4 current clamps, test line, an auxiliary grounding rod, communication line, a printer, etc. The host with 7-inch color screen and the current clamp adopt with wireless communication, and the tester also has Bluetooth communication. After downloading the APP, can test and view the test result on your mobile phone. The tester is equipped with built-in printer, which can print test result on site.The tester can store 100 sets of data and upload test result through the USB interface and the upper computer software to realize functions such as reading, reviewing, saving, reporting, and printing of historical data. The tester shell adopt with waterproof protection box, which is anti-collision, anti-fall, and waterproof (protection level IP65),strong, safe and durable. The tester is also equipped with a large-capacity rechargeable lithium battery pack, which is especially suitable for use on outdoor construction site.

1. Four-clamp method measure the pylon earth resistance without unbuttoning, which is fast, safe and greatly reduce labor intensity.

2. The current clamp and the host adopt with wireless communication to avoid messy connection line and cumbersome storage at the test site, time-saving and efficient.

3. The two-, three- and four-wire method can be used for measurement of earth resistance, soil resistivity, earth voltage and AC leakage current.

4. The current clamp can be used independently as clamp tester.

5. Alarm function, setting alarm threshold.

6. Memory, 2000 sets of data storage.

7. USB interface, data upload function.

8. Bluetooth communication.

9. Large-capacity lithium battery.

10. Built-in printer
