It has 1 Pt Redox electrode at 30 cm from the probe top side, and 1 Temperature electrode (NTC) at 29 cm from the probe top side.

For handheld measurements, it can be connected to our Swap Wireless Interface (SWI). The measurement data can be displayed, stored and e-mailed with an Android phone using our free app.

For standalone measurements it can be connected to a datalogger with an SDI-12 input.

Because the reference electrode (integrated in the black pointed tip) and Pt half-ring electrode are integrated in one probe, soil Redox measurements are very easy to perform.

The integrated reference electrode contains a harmless 3 M KCl gel for long-lasting soil Redox measurements. The Pt half ring is embedded in a glass-fiber reinforced epoxy housing, that can be cleaned very easily (in between measurements).
