T-3720 ~1200Ω earth resistance clamp tester

T-3720 earth resistance clamp tester is a ground resistance measurement instrument. It uses a new generation of LCD black screen backlight display and microprocessor technology. Ω+A synchronously displays the grounding resistance by induction. It does not need to measure the grounding system in the loop. It is safe and fast to disconnect the earthing lead off line without auxiliary electrodes. It is widely used in telecommunications, electric power, meteorology, engine room, oil field, power distribution line, tower transmission line, gas station, factory grounding grid, lightning rod and so on. The instrument has the characteristics of accurate, fast, simple, stable and reliable.

T-3720 earth clamp tester is controlled by microprocessor, accurate detection of earth resistance, leakage current. It uses fast filtering technology to minimize interference. At the same time, 500 groups of data can be stored. It can monitor data online through monitoring software, upload USB data to PC, and have unique functions such as numerical maintenance and intelligent alarm prompt. This model T-3720 earth resistance clamp meters are particularly suitable for measuring earth resistance in various installations such as buildings, pylons and RF transmitter sites without system disconnection. In addition, they can be used for the inspection and verification of lightning protection systems and virtually any installation where a current loop can be generated.
