LOL i almost made a post with the same exact question and PH meter on ebay. good thing i read around before posting. I emailed the seller asking about its brand and reliability just to be sure before buying. Im a soil grower but have some PH problems with my water so im in need of a good meter. hopefully it aint a cheapo knockoff that breaks quickly.
should i go and pick up this meter too? whats the good and bad about it?

so far so good
everything has been working
the only bad thing i have found is it takes the 6.86 calibration solution instead of 7.01 and the local hydro store only has 7.01
so i got some ordered and should have in the middle of the week
but i have the 4.01 and the storage solution already
doh i just ordered mine today and some solution but i got the 7.01 too. where did you order the 6.86 calibration. just gotta get some storage soultion and that 6.86 now. went to the only hydro shop on the island today to get some PH up and down along with some grow big and tiger bloom but didnt see any storage solution. maybe ill check it out again tommorrow or maybe ill just call first and save me a trip there.
i bought this 1 cause i didnt have enought money for a big bottle
20 ml 6.86 pH Calibration Solution, Clearance | Gemplers
next time ime gettin this big set
Apps Laboratories - pH solutions
i might pick up some on ebay 100ml for $10 if they can ship to me, if not im gonna check some pet stores and hope for the best.
should be getting my meter by mid next week and i hope ill have the fluids around the same time. gonna keep those sites on my favs just in case my sources come up dry.
stay irie
also try pool shops
got my 6.86 solution in. it came in 25 29ml packs, which i like more than the bottles of ph, seems to get more uses per dollar
at first i thought i was havin a problem cause the 7.01 solution i had was reading 7.3, so i emailed the company and they told me to email them the reading of everything after using the 6.86 solution, and the 6.86 and the 4.01 read correctly. so we are thinking the 7.01 solution could be off
i calibrated everything and so far seems to be working fast and accuratly, and also checked with the liquid test drops too
well i got all my ph needed items, but i have a small prob now. it seems that i can calibrate fine with the 4.01 solution but with 6.89 and 7.01 i get readings of 5.4-5.5. I emailed the sellers with a few questions so hopefully i get some replies soon. maybe i need some of that powdered 6.89 instead of the liquid. i cant even get a 7 calibration now, and i need to test some water for feedings since my girls are in 12/12. AHHHH what to do what to do.
time for a smoke break and think things through
Did you get the same meter? Or did you get a digital one?Quote:

yeah we got the same meter. in the instructions it only says to use a freshly decanted solution of 6.89 or 4.01 to calibrate. i let my solutions sit for a few hours to decant then slowly poured some solution to calibrate. but i always get 5.4-5.5 with the 6.89 solution. dont know if the 2 hour style will work with this type of meter since it locks on to the PH level when done. no adjustment screw or anything i could find. guess im stuck on this for a bit til i can get it calibrated correctly.
