InstructionsRinse electrode in distilled water and gently shake off excess water. Immerse electrode in calibration solution 7.0 for at least 2 minutes then adjust so the meter reads 7.0. Finally, to ensure accuracy, repeat the procedure with calibration solution 4.0 adjusting so the meter reads 4.0.
To prevent contamination of this solution, decant a portion into a smaller container and discard once used.
Never place electrodes in the bottle. Use sparingly – add drops to nutrient solution a little at a time, stir the solution and continue to test pH levels.
Repeat application until desired pH level is achieved. The quantity required for pH adjustment will vary depending on the nutrient strength and the purity of your water.
IngredientsWater, 1,2-Benzenedicarboxylic acid, monopotassium salt
