Zodiac – ST2 sensor – R0827600

The Zodiac R0827600 is a genuine OEM replacement sensor designed for use with Zodiac’s range of automatic pool water treatment and control systems. This sensor is a critical measurement component responsible for monitoring water conditions and feeding real-time data to the connected control unit, enabling precise automated dosing and regulation of your pool water chemistry. As a genuine factory-supplied spare part, it is manufactured to the exact tolerances and specifications required for reliable long-term operation within the Zodiac system.

Sensors of this type are integral to the correct functioning of salt chlorination and water treatment systems. They are typically submerged in the water flow path where they continuously sample and transmit readings to the control unit. A faulty or degraded sensor can cause incorrect dosing behaviour, poor water quality, or system fault alerts — making timely replacement with a genuine part essential for maintaining system accuracy and user safety.

Technical characteristics and compatibility

The R0827600 sensor is a genuine Zodiac spare part confirmed compatible with the ST1, ST3, ST4, ST5, and ZS550iQ models within the Zodiac pool treatment system range. It is engineered to slot directly into the existing installation without modification, ensuring a straightforward like-for-like replacement. Genuine Zodiac components are built to withstand continuous exposure to chlorinated and saline pool water, and are subject to the same quality controls as the original factory-fitted parts. Using a genuine replacement ensures that the calibration and sensitivity characteristics remain within the manufacturer’s intended operating parameters, which is particularly important for systems that rely on sensor feedback for automated chemical management.

Suitability and application

This sensor is intended for pool owners and technicians maintaining Zodiac ST-series and ZS550iQ automatic water treatment systems. It is suited for both residential and light commercial pool installations where these Zodiac control systems are in use. If your Zodiac controller is displaying sensor-related error codes, producing inconsistent dosing results, or if the sensor has reached the end of its service life, the R0827600 provides the correct genuine replacement. It is not a universal sensor and should only be installed in the compatible Zodiac models listed above. Installation should be carried out in accordance with the Zodiac system installation and maintenance documentation.
