Hey thanks eveyone thanks for the comments, its a new meter came with fresh batteries . And Yes
@Og_punkgenetics I agree I love the meter I cleaned it for the first time yesterday with the cleaning solution. It seems to have a orange stain on the white contact point, u think I should exchange it for a new one lol? I got 1-2 days on my 30 day return lol but today I bought the ph test drops and it seems like my tap is 7.0 and my 7.0 solution is 8.0 at least thats what the test says and my 4.0 solution is correct at 4, should i just use my tap to calibrate? Lmfao it seems like solution is always going to go bad it went bad in 3 weeks but maybe I didnt close the cap tight enough once? Idk ill try and get 7.0 solution tom and take it from there. I also got a budget ph meter from
vivosun Which calls for 3.8 and a 6.8 solution would that be fine to use on it and then just round up .2?
