Name that ph level

[diablo243]

Ok having a frustrating time getting different readings from different test and devices. Did a vinegar soak and recalibration on my RKL ph probe and it still only wants to read 7.8 API test kit to me says 8.2 but a dip strip looked more like 8.0 so what are people's opinions on what this test is reading please. Thanks!

Eh I don't know now looking at this pic I'm not sure.... Ughhh being color blind sucks!!!!

I'm not color blind but it looks the closest to 8.0. It's defiantly a tough match up.

7.8-8.0

All those pH values are OK.
