400 Strips Plastic Ph Test Strips, Universal Ph 0-14, Litmus Test Paper with Storage Case for Saliva Urine Water Soil Testing Pet Food and Diet Ph Monitoring

Good Quality and 200 tests is nice. I tested tap water, bottled water ,vinegar, home made Electrolyte drink, and hydrogen peroxide, and bleach; all tests seemed to work great!!! So the Ph test work , would buy again.....

Strip colors are accurate to chart. Simple to use. And price was fantastic

The media could not be loaded. Para un entorno casero son muy buenas teniendo en cuenta el precio y la cantidad de tiras que vienen, lo usé en un entorno de galvanoplastia casera, para unos baños de niquel y me funcionaron muy bien, aunque aveces tenía que gastar hasta 20 tiras para regular el pH por qué no son del todo precisas, así que si necesitan mucha pecision talvez deberían invetir en algo mejor

I am a chef, cna and cosmetologist. PH has played a vital role in each field. I test foods, products for skin, hair and nails.

I previously gave these a negative review because I was using trem wrong. I didn't realize that you have to inseert the end of the strip with the four colored boxes to get the color change. I thought any part of the paper would work, because that's what I've always seen in the past. That being said, I find these to be extremely hard to use. The color change is difficult to see. I like a tester whre you dip it and it changes color according to the PH. I dunno, these just seem weird to me.

Very useful

Accurate and easy to use.

Every strip I have used comes out to the same PH. I tried hard soaps, liquid soap, water and my saliva.
