NEW! - EcO Smart Monitor for saltwater

Our new EcO monitor is now compatible with saltwater pools and hot tubs.

Just Let It Float

You just need to put EcO in the water after having followed the step-by-step guide. Using the iopool app, you will then be able to get in real-time readings: pH level, ORP or disinfection capacity, and water temperature.

Why ORP? Oxidation-reduction potential (ORP) or redox determines the general water quality of a swimming pool. It measures the overall level of sanitation. 


  • Discreet;
  • User-friendly;
  • Improved precision;
  • Comes with the free iopool app;
  • 2-year warranty.

EcO + iopool App =  balanced, safe, clear water 24/7

You can free download our app on Apple Store (IOS) or Play Store (Android). 

Iopool Bluetooth/Wifi Gateway

  • Eco must stay underwater at all times. Prolonged contact with air may damage the sensors. 
  • EcO must be stored adequately (following the instructions on the app) when water temperature is below 15 Celsius Degrees or  59 Farenheit Degrees. 

Commonly Asked Questions

What about test strips?

Test strips are still useful to measure the level of stabilizer, water alkalinity, and water hardness. The app will suggest you perform test strips at the set-up stage and whenever it is needed. 

What if I am not satisfied?

If you were not fully satisfied, you can use the 30-day money-back guarantee.

Can I use the monitor with non-iopool branded pool chemicals?

Sure. However, for the best experience, we recommend using our iopool pool maintenance chemicals. Why? Because the recommendation engine is designed around our products.

What is the lifespan of EcO?

EcO has a lifespan of 2 years, after which you can order and replace the monitor: replacement module. Buying this device extends the warranty for two more years.

What is the warranty period of EcO?

The EcO probe is guaranteed for 2 years from the date of purchase.

Do I need to pay for any subscription?

There is no subscription

Can I access my data all around the world?

Yes thanks to iopool Bluetooth / Wi-Fi Gateway (included in this pack). By default, EcO uses Bluetooth Low Energy (BLE) technology to send data to your smartphone, so you must be near the pool (approx. 9 m).

What does EcO measure?

The analyzed parameters of the EcO probe are:

  • Water temperature;
  • Disinfection capacity (Redox capacity, ORP);
  • pH (hydrogen potential).

    Je suis très satisfait pour le moment de l'utilisation de mon Eco Start. Dernièrement il m'a alerté sur un dysfonctionnement de mon electrolyseur de sel suite au paramètre "capacité de désinfection " qui était trop faible . Et en effet j'avais la led de signalement d'un défaut qui clignotait en rouge suite à une circulation de l'eau qui était trop faible à cause de la "chaussette de filtration " qui était colmatée et qu'il était necessaire que je lave.
    Bravo à IO Pool !!!!!!
    Quand on est content il faut le faire savoir aussi….
