Jandy ORP Sensor

This sensor measures the oxidation-reduction potential (ORP) of your water, which is a reliable indicator of how effectively your sanitizer is working. It provides real-time data to your control system, allowing it to automatically adjust chemical levels to keep your pool water clean and balanced.

This specific model (R0894400) is designed as a direct replacement for the Jandy TruDose Chemical Controller. If you are using a different Jandy automation system, please verify your controller's manual to ensure it supports this specific ORP sensor model.

Yes, this sensor is fully compatible with saltwater pool environments. It is built to withstand the specific chemical demands of salt-chlorine generator systems while providing accurate readings.

ORP sensors are consumable items that naturally degrade over time due to constant exposure to pool chemicals. While lifespan varies based on water chemistry and maintenance, most users find they need to replace the sensor every 1 to 2 years to maintain accurate readings.

Installation is generally straightforward if you are comfortable with basic pool equipment maintenance. However, because it involves the plumbing and electrical integration of your chemical controller, you should follow your system's manual carefully or consult a pool professional if you are unsure about the process.
