Hi, I was wondering which one is more accurate. Because sometimes its close but sometimes its way off.
For my TA test:
The first test I got:
5 Way: 80
The second test after adding acid (a lot of it because of new plaster and high PH within a 24 hour period):
5 Way: 110
I also noticed the PH of the two are slightly off but pretty close. I would say it's off by .1 to .2 at most
TC is pretty accurate of the two
