Anyone know a decent ph/ppm/temp meter

Im looking for a decent and i know you usually have to pick one or the other but good and cheap meter that does Ph/PPM/temp in the range of 10-20 bucks

Hah, for that cheap? No way.. The Hanna line (not the greatest) starts at around $80 or so for pen types.

all in one pens for $20? never! I have a PH pen off amazon for $3 from newer that has lasted 7 months but I did just order a new one just in case and they raised the price to $8.

gotta a link and does it do ppm?

and ph on the meter?

I own this! Not cheap but accurate, dependable, waterproof. PH and PPM's are numbers that should be exact, not saying that you can't get good numbers with other stuff. But I have calibrated once, and even when I did it really was only off .1 or so.

oh sorry I just read your 10-20 bucks range, opppps

Ebay is where I bought my first pens before I upgraded to a blue lab and Eco tester2 ill be honest these are a very important instrument to have with hydroponics
I got both my first ppm and ph meter on ebay for around 20.00 total maybe 25.00 ph meter broke after one year but did ok and ppm meter still works but gave it to a friend just starting out cause I upgraded mine get liquid ph tester to compare to your ph pen cause the cheap ones are tough to calibrate. I still test mine with liquid too and check ph every day and ppm
ph keep around 5.5-6.2 I like mine at 5.8 ppm start off slow with nutes you can always add more.
