200 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 Monitoring

These work great. With the 4 different colored squares, I am more confident that I have an accurate Ph level than with the single colored paper strips. The 4 squares are secured onto a longer plastic strip making it easy to measure readings without getting solution on yourself. I found the price reasonable. I do go through a lot of these, I measure the ph level before generating my solution, again if I make any adjustments, after generating it, and before using if the solution has sat a while. You can cut these vertically in half or 3rds to stretch them. I find the current price point very reasonable, and plan on making these a regular purchase.

Exactly what I expect. Good product for my application.

Works great. Easy to use. I tried it out in water, saliva, and spaghetti sauce. It was accurate.

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 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.

Me buenos gracias

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.
