TM25r

TM25r

The TM25R grounding resistance meter for high frequency has been developed  to ensure Testing of the power transmission towers grounding (G) without interruption of the power. This is the appropriate tool for a fast, safe and reliable grounding resistance measurement in each tower of a working line transmission, without disconnecting the ground wire.

The TM25R has a Bluetooth interface that allows remote control of it through a tablet with BlueLogg software. With it you can save the photos of the towers and the GPS coordinates of each. It also allows you to record voice comments for each measurement. This equipment is powered with its universal charger, from a built-in rechargeable battery. It is a strong equipment, easy to carry, resistant to the hard weather and geographical features of the tropical and high-mountain regions, that is why it is described as an excellent product for field works under the most severe environmental conditions.
