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.

These work great. Not sure why 4 are pictured...you receive 2 packs of 100 each.

Accurate. I use these to check anything I’m fermenting. Kombucha, chili 🌶️ peppers in brine. I know if the product is shelf stable.

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

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

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.

Package is difficult to open. Results chart is not clear at all.

Me buenos gracias

Ces bandes fonctionnent très bien ! C'est la deuxième fois que j'en commande. Exemple sur ma photo entre un pH 7 et un pH 12. Néanmoins, si vous souhaitez déceler une différence de pH légère, il vous faudra un outil plus précis. Ces bandes sont idéales pour avoir une indiction du pH rapidement, sans chercher la précision de laboratoire. Déjà comparé avec un pH-mètre, les mesures données sont bonnes.

Es perfecto para lo que lo quiero que es comprobar el agua de la piscina y el acuario. Lo que no me a gustado que lo hayan dejado en la entrada del porche porque podría haber entrado cualquiera y se lo podía haber llevado. Otras veces me han llamado y les he dado instrucciones de donde dejarlo cosa que no han hecho esta vez.

Okay... solltest du einen PH test machen, wo man wissen möchtest ob der ph 1,2,3 ganze Zahlen,. Ist der test perfekt . Wolltest du aber einen genauen ph wert ablesen ist das product das falsche und mann sollte auf Tröpfchen Tests oder digitale Hardware zugreifen.

Buona qualità

So easy to use and take reading of pH accurate and instant results. Great for a quick check outs in the products you are making with clear colour indication to seen whether the ph needs any adjustments.
