Can anyone tell me what this is ❓

So I did some test on the thing it works a little when I put it in pH up water it goes all the way past 7 now if I do pH down water than it goes all down now when I water my plants with pH natural spring water the meter reads right before the 7almost on it. So that's seems ok. I think my pH test stick is a piece of shit. I'm ordering one that does it all 185$
