1Set = 80 Strips Professional 1-14 Ph Litmus Paper Ph Test Strips Water Cosmetics Soil Acidity Test Strips With Control Card New

In the Moscow region delivered in 1 month. They look quite worthy. I checked that I fell under my hands. Vinegar 9% showed acidity-3, and water from the tap showed-6. the readings are close to truth. Took to determine the acidity of the nutritional environment for hydroponics. Who needs to take, thank you to the seller.

Works. Left solution of citric acid, рн 1-2, the right solution soda, рн 8-9. In the middle just tap water, рн 7-8. Common litmus paper with learning chemistry. But much larger and very much! Played, happy a elephant.

Quite working indicators. Took for the sake of interest. Left indicator with vinegar, then two after water. After the indicators on the table remained traces, rubbed soda.

While everything shows 7-8. I'll try further. Bullshit is something))) everything has come clearly. Thank you. I hope it's not just a newspaper.

Get super fast, about three weeks is petty, I practice and work, try it with products that had different acides and seen the Colour changing.

The strips came in the mail. Ordered December 20, came on February 3. The goods are well packed, went safely and safely. Not yet checked.
