Common questions

What if I am not satisfied?

We think that once you try EcO, you'll love it! However, if you were not completely satisfied, don't worry: we offer a 30-day money-back guarantee.

Can I use the monitor with non-iopool branded products?

Yes. However, for the best experience, we recommend using the iopool brand since our recommendation engine is designed around our products.

What is the lifespan of the probe?

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

What is the warranty period of the probe?

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

Do I need to pay for any subscription?

No. You can access all functionality without any subscription, including customer support by in-app messenger.

Can I access my data all around the world?

This is possible by purchasing an iopool Bluetooth / Wi-Fi Gateway. 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).

Which parameters are monitored ?

The analysis parameters of the EcO probe are:

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

Moreover, thanks to the initialization process, our calculation algorithms have 3 important parameters:

  • Water hardness;
  • Water alkalinity;
  • Amount of stabilizer (cyanuric acid level).

Have additional questions?

Refer to the dedicated section of our FAQ or contact us via in-app support or on the website.


After initialization, don't remove the EcO from the water. See this article for more information.

Love it - Wish if Measured Hardness….

Great way to keep your spa clean, while reducing unnecessary chemical usage trying to guess with the color strips. Water hardness though is not measured, which would have given this a 5-star review.

Très bon produit facile d’utilisation

Sonde Eco Start

Très bon produit, livré rapidement et bien emballé.
Toutefois, la mise en route est compliquée, très difficile de connecter le Wi-Fi.
Pour ce qui est de la sonde, dommage qu'il faille en changer tous les 2 ans, impossibilité de la charger ou de changer la batterie.
Je réfléchi donc à un autre produit en remplacement dans les 2 ans.
Sinon la sonde fait bien son travail, donne les informations utiles à l'entretien de la piscine et ça c'est vraiment top.
