About This Item
OEM pH Sensor for Pentair AK110 and AK600 Chemical Controllers
The Pentair 744000260 is the OEM replacement pH sensor for the AK110 and AK600 Chemical Controllers. This BNC-connector sensor (blue) is the direct-fit replacement for restoring accurate pH measurement to your automated chemical dosing system.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Electrical control components must be installed or replaced by a qualified electrician or certified pool technician. Do not attempt to service mains-voltage components without proper certification.
The pH sensor continuously monitors water chemistry and transmits readings to the AK110 or AK600 controller, which uses that data to trigger chemical dosing. A degraded or failed sensor produces inaccurate pH readings, leading to under- or over-dosing of sanitizer and pH-adjustment chemicals. Replacing the sensor restores closed-loop chemical control accuracy. The BNC connector type and blue color designation identify this as the pH sensor — confirm the connector type and color on your existing sensor before ordering.

Pro Tip
pH sensors and ORP (oxidation-reduction potential) sensors are often sold as a pair for chemical controllers — confirm you are ordering the correct sensor type before purchasing. The blue BNC connector identifies this as the pH sensor. If your controller is also displaying erratic ORP readings, inspect the ORP sensor (typically yellow or black connector) at the same service interval. Match the part number on your existing sensor to 744000260 before ordering.
