Whats a decent ph meter?

I have this ph meter i got off Amazon and I really think it not accurate. Whats a reasonably priced ph meter someone can recommend. Are the ones that measure ph and ppm any good?

Apera economy level is a great option
Ph 20 I think

Yep the ph20 is a good meter. Cheaper on Amazon though

Perfect thanks guys!!

Apera is the way to go as Blue Labs tend to cost more. I can only say Apera is a fine meter.
