How it is used
pH measures how acidic or alkaline a solution is and is defined as the negative logarithm of the hydrogen ion concentration: pH 7 is neutral, lower values are acidic and higher values alkaline. The tester measures pH electrically with the electrode at the tip of its probe and shows the value on a large LCD, which is quicker and more precise than judging an indicator colour.
- Calibrate at two points with buffer solutions; the tester recognises the buffers automatically.
- Rinse the probe with distilled water and blot it dry.
- Dip the long-reach probe into the sample, which can be in a beaker or a test tube.
- Wait for the reading to settle and record the pH.
- Rinse the probe with distilled water before moving to the next sample.
Typical class uses are checking the pH of acids, bases and salt solutions, following a neutralisation, and testing soil extracts, rainwater and household liquids.
