i just got my ph pen and its being a bitch. im trying to calibrate it but the directions dont make much sense. I put it in water from the faucet and calibrated it to zero. but then when i put it in OJ the ph is not what its suppose to be

ha. yea the instructions say borax but idk where i can buy that. i read somewhere that the ph of oj was arounf 3.5 so i used the water to calibrate to zero then used oj to test it. didnt work

yea you need the pH buffer solution, totally forgot about it, you should be able to find it online, or go to a local hydro shop
