Gossen Metrawatt GEOHM XTRA Earth ground meter

High-precision ground and low-ohm measuring device. The GEOHM XTRA, all of the usual methods of earthing measurement simply and reliably performs.
Highlight is the measuring method for inspection of lightning protection systems under nearly real conditions with the different types of pulse measurement method. Furthermore, a professional grounding analysis on the basis of the measured interference voltages as well as interference frequencies can be carried out. In combination with the built-in GPS module, all measured values together with the GPS co-ordinates are stored. Measurements using different measurement methods:
Earthing resistance with 3-/4-Pol-Messverfahren
Selective earth resistance with 3-Pol-Messverfahren with clamp-on ammeter/benefit: no influence on parallel earth!
Earth resistance with 2 clip-on ammeter or ROGOWSKI coils up to 4 m/benefit: No separation of the grounding system required!
Specific Erdwiderstander Wenner method method - for the creation of floor expert opinions.
Leakage current/power measurement - with the help of clamp-on ammeter or flexible current sensor
Low ohm measurement with 200 mA according to EN 61557-4/VDE 0413-4 ≥
Built-in GPS module for position storage of test objects
Your advantages
Cost savings - one device for many measurement tasks
Time saving - simple troubleshooting by professional grounding analysis
Easy to handle - through intuitive user guidance, graphic display and help function
Fast reproducibility - with modern data management
ROBUST THROUGH MEASUREMENT CASE-use in rough environments and easy transport.

The extensive measuring accessories can earthing measurements and resistance measurements in any environment and of any grounding, lightning protection system is also without separating of the erders can easily be realized.
Key features
The GEOHM XTRA can far more than only the common methods of earthing measurement simply and reliably performs. In combination with the built-in GPS module, all measured values together with the GPS co-ordinates are stored. Highlight is the measuring method for inspection of lightning protection systems under nearly real conditions with the different types of pulse measurement method.
