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 (0.7 oz / 20ml)
  • 1x pH 7.00 calibration solution (0.7 oz / 20ml)
  • 1x OPR +468mV calibration solution (0.7 oz / 20ml)

Calibrating the EcO allows the analyzer to adjust to wear and tear on the electrochemical probe and thus take more accurate measurements, longer.

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?

  1. Take the EcO out of the water, remove the silicone cap, and rinse the sensor with clean water.

  2. In the iopool app, go to "My pool/spa > Devices > EcO" press "Calibrate my EcO" and follow the steps in the application carefully.

  3. Once the calibration is complete, replace the silicone cap in the test position and put the EcO back in the pool or spa.

Never received Kit

Bad customer service. No one called or emailed me back. Little disappointed I was looking forward to use my device. Even bigger disappointment was that I spent all that money on my monitor and it didn’t even come with the Calibration tester.

Help needed

No directions came with the kit- how to use it and how to reset the device- that would have been extremely helpful.


We had some bottle neck with the process but I received all the support I needed all the way to the end. My device working well and our pool
Is looking great!

Ph 4 was nearly empty

Tried to calibrate but don’t think it worked. The ph 4 bag was nearly empty compared to the other pouches.
