Analyze Your Water with EcO

Swimming pool maintenance can be tedious. That's why our team has developed EcO, an intelligent and connected probe suitable for both pools and jacuzzis/spas.

Let It Float

All you need to do is place EcO in the water after following our step-by-step guide. Thanks to the iopool application, you can then obtain real-time readings from the water analyzer: pH level, ORP (oxidation-reduction potential) or disinfection capacity, and water temperature.

ORP, or oxidation-reduction potential, determines the overall quality of pool water. It measures the general level of sanitization.


  • Discreet: EcO blends seamlessly into your pool.
  • User-Friendly: Simply let it float.
  • Improved Precision: Reliable measurements for consistently clean water.
  • Free iopool App: Receive personalized maintenance recommendations.
  • 2-Year Warranty: Enjoy the assurance of a quality product.

This Package Includes

  • The EcO analyzer;
  • Startup guide;
  • A measuring spoon;
  • 3 test strips;
  • Free access to the iopool application;

iopool Application

The iopool application provides you with maintenance recommendations based on data collected by the EcO probe. Say goodbye to guesswork! The application informs you when and how much product to use to maintain your pool's chemical balance. EcO + iopool Application = Balanced, Safe, and Clear Water 24/7. You can download our application for free on the Apple Store (iOS) or Play Store (Android).


Treatment Spa Pool

*In addition to a chlorine-based treatment

But There's More…

Bluetooth connectivity allows you to access data from up to 9 meters away. Want to monitor your data from anywhere? You can do so by purchasing a iopool Bluetooth/Wi-Fi gateaway, or by choosing our bundled offering EcO Start and Connect.


  • EcO must always remain submerged in water. Prolonged exposure to air can damage the sensors.
  • Incompatible with salt-treated pools/spas. For this type of treatment, please consider EcO Start Salt + Connect.
  • EcO must be stored appropriately (following the application's instructions) when the water temperature is below 15 degrees Celsius.

Frequently Asked Questions

What about test strips?

Test strips are always useful for measuring stabilizer levels, alkalinity, and water hardness. The application will suggest performing strip tests during installation and as needed. For more information, visit our blog.

What if I'm not satisfied?

If you're not entirely satisfied, take advantage of our 30-day money-back guarantee.

Can I use EcO with non-iopool brand pool chemicals?

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

What is the probe's lifespan?

EcO has a lifespan of 2 years. After that, you can order a replacement module. Purchasing this module extends the warranty for an additional two years.

What is the probe's warranty period?

The EcO probe is covered by a 2-year warranty from the date of purchase.

  • Do I need to subscribe to a subscription?

No, there is no subscription required.

Can I access my data worldwide?

Yes, you can do so 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 need to be near the pool (approximately 9 meters).

What parameters does the probe monitor?

The EcO probe monitors the following parameters:

  • Water temperature;
  • Disinfection capacity (oxidation-reduction potential, ORP);
  • pH (hydrogen potential).
