JNW Direct Universal pH Test Strips (0-14) - 150 Quick & Easy pH Testing Strips - Ultimate pH Balance Test Strips Kit - 150 Strips

Purchased these to use for my dog. Loved having so many and that they were so easy to use. My veterinarian recommmended them. Would order them again.

this is an instant test, and i suggest you try it out a few times to get to where you can read the colors quickly. it is not hard to do, just need to know what to look for. i have used this on pool water, pond water, city water and other sources. no issues, it agrees with the electronic version i bought later

These test strips make testing water, pop, sauces, urine, skin and hair products, etc., easy. Dip it for a couple of seconds then wait a few seconds and the color changes to show acidic or alkaline according to the color chart on the box.

Doesn’t work. I had to prove that to my self, by testing my plant water which was a store bought gallon of spring water. I checked on the data sheet from the distributor. it was supposed to have a p.h. of 6.8 and the strip seemed to be reading close to that. Then I used another strip to test straight vinegar from my kitchen and to my surprise the strip was reading the exact same as the bottled water. So I then realized there was literally no difference from a fresh unused strip and the strips I used in either test. So I ran the test twice more with real lemon juice and then some Hydrogen Peroxide. Still no change in the strips used. These have been a waist of my hard earned cash. I can not recommend anyone making it their wast of money

I got these to check the acidity of Kumbucha tea during brewing Have not figured out what I am reading on them They are not very user friendly and there is no real explanation on the box of the 4 different columns I am looking at. I am sure they work fine I just am not sure what I am seeing. Their ebook really does not help
