Best For:
-
Substations
-
Utility networks
-
Renewable energy installations
-
Lightning protection systems
-
Telecommunications sites

CA6416 Earth Ground Clamp
The CA6416 enables fast earth loop resistance testing without disconnecting conductors or driving test stakes into the ground. Simultaneously displaying earth impedance, leakage current and ground voltage, it provides a quick and safe method for routine earth testing. Storage for 300 measurements and CAT IV 600V safety rating make it ideal for professional use.
Best For:
-
Routine maintenance inspections
-
Building services engineers
-
Commercial electrical testing
-
Telecommunications installations

CA6417 Bluetooth
Earth Ground Clamp
The CA6417 builds upon the capabilities of the CA6416 by adding Bluetooth connectivity, enhanced memory and software integration. Users can store up to 2,000 time-stamped measurements and transfer results directly for reporting and analysis, helping streamline compliance and maintenance programmes.
Best For:
-
Asset management programmes
-
Electrical compliance reporting
-
Large industrial facilities
-
Engineers requiring digital record keeping

CA6418 Earth Ground Clamp
The CA6418 is specifically designed for testing earth resistance on earth bars, straps and conductors where standard round-jaw clamps may not fit effectively. Its unique oblong jaw design accommodates rectangular bars up to 30 x 40 mm and 20 x 55 mm, as well as conductors up to 32 mm diameter. It simultaneously measures earth resistance and leakage current while offering excellent visibility through its high-contrast OLED display.
Best For:
-
Multi-earth installations
-
Earth bars and copper tape systems
-
Substations
-
Railway infrastructure
-
Lightning protection systems
