Apex pH Probe

[Enigma]

I'm waiting for pH10 calibration fluid in the mail.

I'm recording the Apex results as my pH, but I'm backing it up with my API test. My API test tends to show my pH a little higher than the Apex probe.

The probe records between 8.11 and 8.23. It took a little bit (couple of hours) for it to settle in. That first reading may have been erroneous.

I'm pretty confident in it. If it is out, it isn't out by much.
