Most common questions

What if I am not satisfied?

There is little chance that this will happen because trying an EcO is adopting it! However, if you were not completely satisfied, don't worry: we offer a "Satisfied or refunded" guarantee valid for 30 days after purchase.

Can I use the probe with another brand of products than iopool?

Yes. However, for the best experience, we recommend using the iopool brand as our recommendation engine is based on our products.

What is the life of the probe?

EcO has a lifespan of 2 years, after which you will have to order a replacement module including a new battery and sensors. Buying this module extends the warranty for two more years.

What is the warranty period for 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 functionalities without any subscription, including customer assistance by chat.

Can I access my data around the world?

This is possible with the iopool Bluetooth / Wi-Fi Gateway included in the EcO Start Premium pack only. By default, EcO uses Bluetooth Low Energy (BLE) technology to send data to your smartphone, so you have to be near the pool (approx. 30 feet).

What are the water parameters monitored by the probe?

EcO monitors

  • The water temperature;
  • The disinfection capacity (Redox capacity, ORP);
  • The pH (hydrogen potential).

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

  • The hardness of the water;
  • The alkalinity of the water;
  • The amount of stabilizer (cyanuric acid level).

Your question is not on the list?

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


  • After initialization, you can't get EcO out of the water. See this article for more information;
  • EAN code: 5419980032898.

Quelle est la durée de vie de la sonde ?
EcO a une durée de vie de 2 ans, après quoi vous devrez commander un module de remplacement (89 €) comprenant une nouvelle batterie et des capteurs. L'achat de ce module prolonge la garantie de 2 années supplémentaires.

-> Je pense que tout est dit : produit jetable au bout de 2 ans a moins de s'acquitter a nouveau de 89€ ...


Malheureusement, cela est valable pour toutes les sondes connectées du marché. Les capteurs, étant des capteurs chimiques, s'épuisent au fur et à mesure des analyses et ont donc besoin d'être remplacés après un certain temps.

Bonne journée,
L'équipe iopool
