    Can anyone vouch for this pH tester? Or recommend another? I'm sick of trying to guess the test tube colors and I'm going to be doing hypo treatment monitoring pH twice a day, so I might buy this.

    Very accurate tester, as are all the Hanna instruments.

    Thanks. How often do you calibrate it?

    It says frequently. I would check calibration every month or so. If it is way off, check it more frequently if it is spot on, maybe every couple months.
