Zodiac – Complete replacement electrode cell TRi 10 – R0758400

The Zodiac R0758400 is the complete replacement electrode cell designed specifically for the Zodiac TRi 10 salt water chlorinator. As the core electrolytic component of the chlorination system, this electrode cell is responsible for converting dissolved salt in the pool water into free chlorine through electrolysis. Over time, electrode cells naturally degrade due to scale build-up, mineral deposits, and general wear from continuous operation. Replacing the cell with this genuine Zodiac spare part restores the chlorinator to its original performance, ensuring reliable and consistent chlorine production without the need to replace the entire unit.

The electrode cell produces a chlorine output of 10 g/h, which is calibrated to meet the sanitation demands of residential pools within the recommended capacity range for the TRi 10 system. The cell dimensions are approximately 300 mm in length and 100 mm in diameter, making it a direct drop-in replacement that requires no additional modifications. This is an original Zodiac component, ensuring full compatibility and maintaining the performance and warranty integrity of the parent chlorinator.

Compatibility and technical details

This replacement electrode cell is compatible with the following Zodiac salt water chlorinator models: Zodiac TRi 10, Zodiac TRi Expert 10, and Zodiac eXO iQ 10. It is important to select the correct cell model that matches your specific chlorinator output rating. Zodiac offers this electrode series in multiple output versions — 10 g/h (R0758400), 18 g/h (R0758500), and others — so always verify your existing unit before ordering. The R0758400 is the 10 g/h version and must only be used with TRi 10-rated systems. Installation is straightforward: the cell connects directly into the existing plumbing housing of your chlorinator without the need for special tools or extensive technical knowledge.

Suitability and buying context

This electrode cell is intended for pool owners who use a Zodiac TRi 10, TRi Expert 10, or eXO iQ 10 salt chlorination system and are experiencing reduced chlorine output, error codes related to cell performance, or visible electrode degradation. Replacing the cell is a cost-effective maintenance measure compared to replacing the entire chlorinator unit. The TRi 10 system is generally suited to smaller to medium-sized residential pools. If you are unsure whether this cell matches your system, refer to your chlorinator’s model number and cross-reference it with the R0758400 part number. Using a genuine Zodiac replacement cell ensures optimal electrolysis efficiency, longevity, and compatibility with the original controller and flow sensor assembly.
