Ph probe calibration

[Scotty333!!!]

Guys
I didn’t notice the temperature of rodi needs to be 30 degrees when calibrating my ph probe
The water was more like 15 degrees , I did the 9.18 but not the 6 and 4

I guess it won’t be accurate now?

I calibrate mine to the aquarium temp following Apex directions. But, this is the first pH monitor I’ve ever owned in 40+ years in the hobby

It’s my first too, never bothered with ph but since I got the tester for the tds it also measures salinity which is waaay out , ec, orp , temp

Let’s ask @kharmaguru he’s a guru of more than Kharma.

Ya, it will be off a bit likely. I honestly haven't calibrated mine since I got it and it's likely off too. I just watch the trends on the graph and that's enough info for me...
