How to Use a pH Tester

A pH tester is a device that measures the pH of a liquid. pH is a measure of the acidity or alkalinity of a liquid, and it is expressed on a scale of 0 to 14. A pH of 7 is neutral, while a pH below 7 is acidic and a pH above 7 is alkaline.

pH testers are used in a variety of applications, including:

  • Water testing: pH testers can be used to test the pH of water in pools, spas, and aquariums.
  • Soil testing: pH testers can be used to test the pH of soil in gardens and farms.
  • Food testing: pH testers can be used to test the pH of food products, such as wine, vinegar, and fruit juices.
  • Medical testing: pH testers can be used to test the pH of urine, blood, and other bodily fluids.

To use a pH tester, follow these steps:

  1. Calibrate the pH tester. This is done by placing the tester in a calibration solution of known pH. The tester will then adjust its readings to match the calibration solution.
  2. Rinse the pH tester with distilled water. This will remove any residual calibration solution from the tester.
  3. Dip the pH tester into the liquid you want to test. The tester will then display the pH of the liquid.
