Alka pH test strips 100 pieces

Productcode : 8141155

With pH strips you can easily measure the acidity of liquids. A fluid is acidic if the pH is lower than 7 and a fluid is alkaline when the pH is higher than 7.

Even the pH strip dips into the liquid color of the strip compared to the color card, and you know the acidity!


  • For measuring the urine: dip a pH strip 1 second in the morning urine. It is important to make the measurement as quickly as possible, since the acidity of the urine can be influenced by the reaction with carbon dioxide (CO2) from air.
  • For measurement via saliva: Make sure you have at least 1.5 hours in advance has nothing to eat or drink (even water). Swallow a couple of good mouth and tongue dry. Produce then some saliva and place the strip with the color planes down on the tongue. The most accurate measurement you get when your body is sober. Then compare the color of the strip with the color card of the box.
