Soil Redox probes

The latest lineup of our soil redox probes

Redox – also called ORP – is an important soil parameter for monitoring soil oxidation and reduction processes as used in, e.g., wetland studies, agriculture, archeology and environmental research. The SWAP Redox probes allows processes to be monitored continuously, and direct measures can be taken based on the obtained sensor data.

Our soil Redox probes are available in 12 standard versions: 9 analog and 3 SDI-12 probes. We also offer custom-made soil Redox probes and a reference electrode.
