Hi guys,
Just went to calibrate my pH probe on my frag system and have discovered a weird issue and wondered if anybody else has noticed this? So I have the pH 10 reference solutions but in the drop-down menu within the calibrate pH probe task, there is only pH 4 or 7 reference solutions. Am I missing something? Please see below some photos. I do see it mentions low pH calibration solution. Do I just have the wrong solution?
