There is gel on the tip of the pH probe probably not a good idea to use soap and a brush on delicate sensors.

Hello, thank you for the video. It was very helpful. Where did you get the calibration station that holds all of your solutions?

[@wegrow4859]

Thank you! Unfortunately, that station is only available for retailers who are Blue Lab certified and carry their products.

Alright, thanks for the response.

Hello
I can't calibrate my HI 98129.
I'm using a new solution of 1413 microsiemens, but the screen shows WRONG.
What could be the problem? Thanks
