The ICO Pool V2 floating pool analyzer with salt measurement is the improved version, launched in 2026, of the ICO floating analyzer with Artificial Intelligence specially designed to measure the main parameters in pools with salt electrolysis.
It measures in real time the different parameters of the pool water and transmits them to your app, either via WIFI or by radio via SigFox.
TheICO Smart Pool digital pool analyzer is the perfect solution for the analysis of your pool water.
Receive recommendations and alerts to keep the water always clean and in perfect condition for bathing.
It allows you to measure pH, redox, salt and temperature accurately and in real time, issuing alarms to your mobile phone when any of the parameters is out of the selected range.
A version of ICO Pool is available for traditional chlorine pools (not disinfected by salt chlorination).
What are the main differences between Ondilo ICO V1 and Ondilo ICO V2 launched in 2016?
ICO is a connected water analyzer for pools and spas that allows real-time monitoring of key parameters such as pH, disinfection (ORP), temperature and, in the saline versions, salt level, sending alerts directly to the smartphone. In April 2024, ICO V2 was launched, an evolution designed to be more robust, simpler and more accessible than ICO V1, while maintaining reliability in water balance monitoring. The new version incorporates reinforced electronics, simplifies use by eliminating the power button and adjusts the price to reach a wider audience, especially in home installations and spas.

What is redox and how does it relate to free chlorine?
The potential redox (also called ORP: Oxidation-Reduction Potential) is a value that measures the oxidizing capacity of water, i.e., its ability to destroy organic matter, bacteria, viruses and other contaminants. It is expressed in millivolts (mV), and the higher the value, the greater the disinfectant capacity of the water. In the case of pool water, the redox is a reasonably inexpensive option to know, indirectly, if the water has sufficient disinfectant.
A properly disinfected pool should maintain a free chlorine concentration between 1 ppm (part per million) and 2 ppm. If the concentration falls below this threshold, the disinfectant capacity of the water is reduced, increasing the risk of proliferation of microorganisms. On the other hand, if this range is greatly exceeded, the water can become aggressive for the skin, eyes and mucous membranes of bathers, in addition to generating unpleasant odors and deteriorating materials.
Many control systems use redox probes to activate or deactivate chlorine production depending on the actual need for disinfection. Although redox does not measure free chlorine concentration, there is a correlation between mV in water and disinfection capacity.
To establish the appropriate level of redox, the pH level, water temperature and alkalinity level must also be taken into account. In the following table we offer an approximation of the relationship between redox and free chlorine for a pool with temperature 25ºC and alkalinity at 100ppm.
| Free chlorine (ppm) | pH 7.0 | pH 7.2 | pH 7.5 | pH 7.7 | pH 8.0 |
|---|---|---|---|---|---|
| 0.5 | 735 mV | 720 mV | 695 mV | 682 mV | 668 mV |
| 1.0 | 760 mV | 743 mV | 716 mV | 703 mV | 689 mV |
| 1.5 | 772 mV | 755 mV | 731 mV | 716 mV | 702 mV |
| 2.0 | 780 mV | 765 mV | 740 mV | 725 mV | 712 mV |
| 2.5 | 788 mV | 772 mV | 746 mV | 732 mV | 718 mV |
| 3.0 | 794 mV | 778 mV | 753 mV | 739 mV | 724 mV |
| 3.5 | 799 mV | 783 mV | 758 mV | 744 mV | 729 mV |
| 4.0 | 803 mV | 787 mV | 762 mV | 748 mV | 733 mV |
* Adequate free chlorine levels should be between 1 and 2ppm, so it is always recommended to take as a reference the value of 1.5ppm or 2ppm to avoid an excessive drop in the level of free chlorine during the influx of bathers.
