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

I saw some reviews that suggested that these pH strips didn't work, but they worked perfectly for me. I was able to measure changes in the pH of my hydroponic system without any challenges, and it was easy to match up the color markers with the corresponding PH in the chart using the combination of the 4 color bands.

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.

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

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

Very useful

These strips do not work right. I have tested quite a few things that are 5% and above in acidity and they all register at 2%. I will not be buying again.

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.
