So therefore, I got this pH test kit and it works great. Sure, it's a regular test kit and doesn't give you the absolute exact pH like a meter would, but if you need the pH of something to be in a particular range, as in water or nutrient solution for plants, this will certainly do the trick.
But I have to say that whatever you test probably needs to be clear or close to it, since you fill a vial half full and then put 3 to 5 drops of pH testing solution to observe the resulting color change to get the pH. In other words, I'm thinking you may not be able to test the pH of Kool Aid or tea or something, but water or water mixed with plant nutrients where the color is only slightly changed would be fine.
UPDATE: Ok the PH testing portion of this kit is great, HOWEVER, the ph DOWN solution is terrible. DO NOT USE IT. It is made from phosphoric acid which is bad because if you add it to a nutrient reservoir you will have massive amounts of slime growth within a day or two. Toss the PH DOWN and go get something else.

As advertised. No specifics in the instructions, so dosing is trial and error for how much per gallon at each ph range. Read morePublished 2 days ago by Patrick
