What is the recommended depth of placement?** A: Yes it can be submerged. There is no recommended depth beyond simply ensuring the sensor on the tip is exposed to the test sample. The cable is 3 feet long. **Q: Can this probe be left in contact with pool water indefinitely?** A: No, the chlorine is corrosive and will ruin the sensor. **Q: Can use in saltwater? Ph controller?** A: Yes on both accounts **Q: will this work with chemtrol and do you offer an ORP probes** A: If by chemtrol you mean monitoring wall-mounted meters, then we would recommend the 201DJ-C instead. It features more durable and enduring design for long-term water testing and less likelihood of losing calibration to turbulent water as quickly as the 201-C. Yes, there is an ORP probe, the Apera 301PT-C. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Calibracion perfecta *by J***I on 16 January 2025* La calibracion ha sido rapida y perfecta junto con el liquido 7.0 de la misma marca.
