yes i posted pics of the manualYou might try using glass containers as the paper cups may be changing the PH of the solution. Do you have a users manual for the tester? Which brand is it?
This.Make sure you are doing the 6.86 calibration first. I would use glass for this.
i did the 6.86 first the blue one is brand new i have no storage solution but i do not have any glass beakers cups or glassses at allThis.
Soak it on the 4 ph solution overnight and try again.i did the 6.86 first the blue one is brand new i have no storage solution but i do not have any glass beakers cups or glassses at all
It may not be exact you have a cheap meter also.when i did the 6.86 then i would take it out turn it off clean it off turn it back on put it right back in the same 6.86 solution and it would says something other then 6.86
i dont have anymore of the powder solution but i do have this can i not use it at allThe probes should not dry out. And should be stored in a KCL solution. You can make you own cheap.
i do agree but i do not have 100 dollars to buy 1 withHonestly you will spend pretty much the same with all the issues than just buying a bluelab and trusting it.
thanksApera are also good. And you can change the probes when they kak out on the ph60 or better
