The EcO smart water analyzer is a valuable tool for keeping your pool or spa perfectly balanced. Like any device, it needs some basic care to ensure accurate readings and long-term durability. Here are our practical recommendations for maintaining your EcO throughout the seasons.

🧼 Simple regular care

• Rinse the sensors occasionally with clean water, especially after heavy use or a shock treatment.
• Avoid abrasive products or soap — a soft cloth is enough.
• Check the overall condition (no cracks, no persistent deposits).

❄️ Wintering: the right steps

When water temperature drops below 4 °C (39 °F), it’s best to remove EcO from the pool or spa:

1. Rinse and dry the analyzer carefully.
2. Store it in a dry, frost-free place, ideally at room temperature.
3. Use an iopool wintering kit to keep sensors in top condition.

This protects both the sensors and the battery from cold damage.

🌱 Spring restart

• Before putting EcO back in the water, give the sensors a quick rinse.
• Make sure the battery is properly charged.
• Place it back in your pool or spa — it will automatically resume measurements without extra setup.

🔋 Lifespan and replacement

• Sensors last on average 2 to 3 years, depending on usage.
• The battery usually lasts 3 to 4 years with proper winter care.
• Replacement kits are available, extending the life of your EcO without replacing the whole device.

✅ Conclusion

With just a few simple steps, you can give your EcO analyzer maximum longevity and consistent accuracy. Regular care, proper wintering, and a smooth spring restart ensure your water is always under control — all year round.
