SAT-11A/B Single Clamp Earth Tester is widely used in the operation of earth resistance testing for the equipments of the fields of power, telecommunication, weather, as well as the other electrical equipments with the function of easy operation, high-accuracy and good adaptation of testing environment.
Functions:
1. Beyond the limitation of traditional method of earth resistance testing, no assistance poles, with easy and convenient operation.
No error of electrodes arranging, which can get a results in good consistency under the condition of retesting;Equipped with standard testing wrapper which can be used to do the self-testing with accuracy..Qualification:
