Hey...new guy here. Obviously when thinking of Ph testers there are a few options out there that could fit any budget. First would be litmus paper which some people claim to be the most accurate in the economy line. Next u have the drop tester...I've been using this method successfully for years. Cost me $16 and will last at least 6 months. Easy to use and cheap! The best option would be a digital handheld Ph tester which start at around $70 or all in one res mounted with constant feedback. These vary in price according to ur needs. I like the Ph/ec/temp all in one which alerts with fluctuations...must have for hydro setups.

You can get a cheap digital one on ebay for like $5 they work ok.

the only prob I got with the drop tester is when my nute solution is colored it hard to get a good reading (like if mollasses is added) Im gonna go digital

I vote digi as well. Mine I paid around $10 for on eBay.

It's accurate and reliable. It can be a bit slow to measure sometimes, but the results are consistent and accurate enough for my purposes.
I also like using the sachets of pH calibration solutions...it's generally easier to use the pre-measured packet than to find a vial that'll fit the meter and won't waste a bunch of calibration solution. But that's just what works for me.

[KidneyStoner420]

[KidneyStoner420]

Are the yellow and red the exact same, other than the color?

 

[del66666]

yeah mate exactly the same.........doesnt seem any point in spending on a dear 1........had these for months

 

[KidneyStoner420]

Yeah, I've had my yellow one for a while. Just making sure the red was the same.

so i assume your growing hydro, and using this tester, so all is fine no problem with it? did you try to measure pepsi or cola?
was the result 2.5?

are you sure its working fine?? did you try to measure pure ph down? or pepsi? did you get a result ?
are you growing hydro with it ? and all is fine?

the reason i started this post, first , there isn't one like it about ph testers, second i had big issues with mine
made my life measurable , am using this
http://www.amazon.com/gp/product/B002NX0VY2/ref=pd_lpo_k2_dp_sr_1?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0007XSOLC&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0MJNRXFR54M5ET8ETBNE

it can never be calibrated , every reading is different , it only works for water though even sometimes its 7.1 then 7.2 then 7.4, it changes even if i measure Respectively، and it takes around 5 minutes for the reading to stop, and i have to be 5 to 6 feet aways, because once i come close to it the reading goes crazy, i believe its very sensitive to human body electricity, and the best part is it killed my plant , it seems what ever i measure won't go below 5, i tried on pepsi and read online its at ph2.5, guess what, it was ph8, even though it was calibrated the same day, and tried on 37% HCL acid, and it was 5.8ph, and am sure it was supposed to be below 2

so am looking for something that actually works

thank for all the replays and help

Nutra-dip PH/TDS/Temp continuous meter. Note that this meter works great but gives insane readings while the digital ballast is running.
