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 ### ⭐ Funkar inte till Hayward saltklorinator *by A***R on 14 May 2023* Funkade inte alls till vår Hayward Aquarite saltklorinator ### ⭐⭐⭐⭐⭐ Prácticos y eficientes *by C***R on 26 March 2025* Compatible con varios transmisores y de fácil conexión y calibración de campo ### ⭐⭐⭐⭐⭐ sehr gut und günstig *by F***E on 12 October 2024* hab sie Sonde nun die ganze Saison iin Betrieb, funkt einwandfrei absolute Kafempfehlung ## Frequently Bought Together - APERA INSTRUMENTS 201-C Combination pH Electrode, BNC Connector, Polycarbonate-Body (AI1301) - Apera Instruments AI1113 pH Calibration Buffer Solution Kit (7.00, 4.00), 8 oz.
