Usage

Proper maintenance of your pH-meter.

Correctly maintaing your pH-meter ensures a long life span.

Here are some precautions:

  • When buying your pH-meter the electrode will be dehydrated.
    Prior to using it for the first time, leave the electrode to soak in storage solution 4 hours.

  • Use the cover (with a damp sponge soaked in storage liquid) on the electrode after each time. This will prolong its lifespand.

  • Calibrate the pH-meteret prior to using it for the first time.
    Normally with calibration solutions pH 4 og pH 7.

  • Make sure not to contaminate the calibration solution. 
    Never insert the electrode directly into the solution, take out a small portion and soak it from there.
    Throw away used calibration solution - do NOT pour it back into the container!

  • Do not touch the electrode, eps. not with your fingers. If you whish to clean it - use a soft cloth without rubbing the electrode.

Background

pH is a measure of the concentration of free hydrogen ions (H+) in a liquid.

The pH scale runs from 0 to 14.
pH of pure water is 7.

Liquids having a higher concentration of H+ compared to pure water is an acid and has a pH below 7.
Liquids having a lower concentration of H+ compared to pure water is a base and has a pH higher than 7.

The pH may be of importance to what can or will happen to a liquid.
The pH of a liquid can be changed by adding various chemical substances which then adds or binds H+.

The pH may also change with bacterial activity in a liquid with a content of sugar, like milk or water/tea with added sugar. Here, the bacteria convert the sugar and form lactic acid which increases the concentration of H+. Thus, the pH will drop during bacterial activity.

By measuring the pH during production of, for example, cheese, yogurt, kefir and kombucha you may optimize the result.
