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.

Overall Cost is too high

I've found that I have to calibrate my probe at least twice a year. $12.50 is a reasonable price, but once you add in the shipping to the states, it's $25! $50 a year or more to maintain accuracy is too much.

Hi Eric,
Thanks a lot for sharing your feedback with us. We completely understand your point — while the calibration kit itself is reasonably priced, the added shipping costs to the US can feel heavy .

We’re actively looking at ways to make calibration more affordable and convenient for our international customers. In the meantime, your input really helps us prioritize improvements.

Wishing you a great pool season ahead!
The iopool team

I tell you I had my doubts. I really, really did, but it has proven to be everything they say. For anybody that has a pool spa hot tub, this is a must have. Good job, IO pools.

Hi Mr.hotub,

We’re so glad to hear that the calibration kit exceeded your expectations after your initial doubts It means a lot to us that you recommend it as a must-have for hot tubs and spas. Thanks for your trust and kind words!

Best regards,
The iopool team

Not happy to have had to calibrate after only 3 months but seems to be working again.
I do question the accuracy of the orp

Hi Jamie,

Thank you for your feedback!
We’re glad to hear that your EcO is working again after the calibration. We completely understand that having to calibrate after only three months can feel frustrating, and we appreciate your comment about the ORP accuracy.

If you notice any irregularities or experience any issue with your EcO, please don’t hesitate to contact our support team — we’ll be happy to help: https://iopool.com/fr/pages/support

Best regards,

Still not working

My sensor has been very unreliable and I was told to purchase the calibration kit. I did that. It took hours to get the sensor to verify the calibration and now the sensor doesn’t work at all. I’ve contacted customer care and I’m hoping to hear back asap.

Hi Kylie,

Thank you for your message and for sharing these details. We completely understand your frustration with this situation 😟.

We confirm that your request has been received by our customer care team, and our technical team is currently reviewing your case as a priority. You’ll hear back from us very soon with the next steps to help resolve the issue with your sensor.

In the meantime, if you have any additional information (e.g. the serial number of your sensor, purchase date, photos of the calibration readings, etc.), feel free to share it — this can help us speed up the process.

Thank you again for your patience and trust. We're here if you have any further questions!

Best regards,
The iopool team

I did the calibration many times. It didn’t change the readings

Hi Terry,

Thank you for your review and for taking the time to run multiple calibrations

If the readings remained unchanged, it might mean the sensors are stable (which is a good sign) — or that the probe needs a little extra help. Feel free to reach out if you have any questions!

Best regards,
The iopool team
