VIVOSUN pH meter calibration

Hey guys, so while editing this video I realized I said it was reading 4.04 when it was actually reading 4.00 and the actual buffer solution is 4.01, so it was actually a lot closer then the 4.04 that I said it was.

Water temp will mess with your readings. You want your water sitting at 25c
