Gossen Metrawatt GEOHM PRO, High-Precision Earthing and Low-Resistance Measuring Instrument, M592A

Gossen Metrawatt GEOHM PRO, High-Precision Earthing and Low-Resistance Measuring Instrument, M592A, 4012932128345

• Earthing resistance by means of the 3/4-wire measuring method
• Selective earth resistance by means of the 3-wire measuring method with current clamp
• Advantage: no influence on parallel earth electrodes!
• Earth loop resistance with 2 current clamps
• Applications: for example where the use of auxiliary electrodes is not possible
• Advantage: no need to disconnect the earthing system!
• Soil resistivity in m according to the Wenner method - For the preparation of soil assessments
• Leakage current / current by means of current clamp or flexible current sensor
• Low-resistance measurement with ‰¥ 200 mA per EN 61557-4 / VDE 0413-4


• Cost savingsa single instrument for numerous measuring tasks
• Time savingssimple troubleshooting thanks to professional earthing analysis
• Easy handlingthanks to intuitive user prompting, graphic display and help function
• Quick reproducibilitythanks to modern data management
• Rugged measuring caseuse in adverse environments and easy transport


• RS and RH resistance measurements via auxiliary electrodes
• Measurement of interference voltages and interference frequencies
• Measurement even where interference voltages occur in systems with 16.7, 50 and 60 Hz, as well as 400 Hz (with automatic and manual selection of the right measurement signal frequency)
• Measuring voltage selection: 25 or 50V
