This soil Redox probe is specially designed for handheld soil Redox measurements. It can be connected to ORP meters (e.g., the Lutron YK-23RP) with a BNC socket. 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).
For more information, please consult the ORP-30-1-BNC technical specifications.
