For best contact between soil Redox probes and the soil and/or sediment, and to avoid probe damage due to the presence of hard objects (e.g., stones) in the soil and/or sediment, we recommend installing the soil Redox probes with a pre-drill.

The PRE-80 is a 80 cm long drill that is suitable for installing the ‘longer’ SWAP soil Redox probes, e.g., ORP-80-4-B, ORP-80-4-A and ORP-80-4-D.

For questions about the PRE-80, contact us at sales@swapinstruments.com.
