SAT-11A/B Single Clamp Earth Tester is used in testing earth resistance of power, communication, weather and other electrical equipments. It is stakeless, to test multipoint grounds and common grounds, can save time for engineers and specialists
Key Features
No auxiliary ground stakes are required at all, real easy-to-use.
No ground stakes’ error, data have well consistent
Provide testing ring to do accuracy self-testing.
Smart and rugged design, application for field environment.
Detecting and indicating interference signal
Over range alarm
