EcO calibration kit
The iopool calibration kit is a set of buffer solutions, which allow you to accurately calibrate the pH and ORP sensors of your EcO Smart Monitor.
Kit content
- 1x pH 4.00 calibration solution (20ml)
- 1x pH 7.00 calibration solution (20ml)
- 1x ORP +468mV calibration solution (20ml)
Calibration allows EcO to compensate for sensor wear and continue delivering accurate results.
When to calibrate your EcO?
- There is no need to calibrate before first use.
- From the second season on, it is recommended to calibrate at the beginning of each season.
NB: If your Eco is never winterized (indoor pool, spa, Nordic bath,...), we advise you to calibrate every year.
How to perform the calibration?
- Take the EcO out of the water, remove the silicone cap, and rinse the sensor with clean water.
- In the iopool app, go to "My pool/spa > Devices > EcO" press "Calibrate my EcO" and follow the steps in the application carefully.
- Make sure the probe is fully immersed in each solution and no air bubbles are trapped during calibration.
- The
- Use the solutions immediately after opening. Do not store used sachets for later use.
- Once the calibration is complete, replace the silicone cap in the test position and put the EcO back in the pool or spa.
Note: It is normal for the app to ask you to repeat the calibration steps with pH 4.00 and pH 7.00 solutions multiple times. This ensures your sensor is stable and accurately calibrated. If this happens, follow the instructions until calibration is successfully completed.
