Contact: Here are the photos:

Advisor: That's okay, the pH probe for BWT Oxilife 1 should fit.

Contact: Are you sure? I have set a pH value of 7.3.

Advisor: Yes, that shouldn't be a problem.

Contact: Thank you.

Advisor: You're welcome.

Contact: Why does my probe have blue liquid?

Advisor: I don't think the liquid is blue, but rather the plastic is transparent blue.

Contact: BWT always shows 7.0, I wanted to calibrate with liquid and at pH 10 it says out of range. Is this a problem with the probe?

Advisor: This is because the probe is defective and the controller can no longer calibrate. Here is more information: Is my pH probe defective?

Contact: I also need a calibration kit. Which one do you recommend?
