Description
Upgrade your water care with the Astral Pool Viron eQuilibrium Gold Chlorine Sensor (ORP Probe) — a smart add-on that continuously tracks your pool’s sanitising performance and helps the chlorinator fine-tune chlorine output automatically. The result is steadier, healthier water, even when bather load, temperature, or weather conditions shift.
Unlike basic tests that only indicate chlorine level, ORP (Oxidation-Reduction Potential) measures how well your chlorine is actually doing its job. That makes it a great choice for spas, indoor pools, and busy family pools where conditions can change quickly.
Important: This ORP sensor requires the pH Sensor Kit (520135) to operate. When used together, they unlock advanced automation features including Pro Mode and Total AI Mode.
