Description

Earth Resistance Clamp Tester

Model: GRT-100

The GRT-100 is a new generation earth clamp-on resistance tester. The instrument induces a test current into earth systems and measure ground resistance in multi ground installations without needing to disconnect the ground. It offers advanced features, simple operation and CAT Ⅲ 300V safety protection.

The elliptical shaped head design offers improved access to cables and earth straps in space constrained locations. The clamp head accommodates up to 32mm diameter cable and 55mm earth tapes making them suitable for use in power stations, substations, towers and many more facilities. The operation in dark and restricted areas is facilitated by a display with backlight and an audible tone associated with the hold key.

The GRT-100 offers 500 test results storage on-board and on-screen recall, also supports a download of results via USB interface.
