Storage Solution for pH Electrode - 50ml

Storage Solution for pH Electrode - 50ml

Suitable for all electrodes. Prevents staining and degradation of the electrodes.

The maintenance of a pH meter

• The pH meter is a precision instrument. Proper use and appropriate maintenance are important to enjoy your pH meter for a long time. Here are some considerations:
  
• When you purchase the electrode, it is usually dehydrated. First, you let it soak for 4 hours in the storage solution. After each use the cap that slides over the electrode also has to be filled with this storage solution. This keeps your electrode functioning properly for much longer.
• Before the first measurement, the pH meter needs to be calibrated with the buffer solutions. If the pH meter can only be calibrated at one point, use the buffer solution that is closest to your normal measurements.
• When calibrating, be careful that no contamination of the buffer solution occurs. Therefore never insert the electrode directly into the bottle, but instead measure by pouring a small amount in a separate cup. After calibration throw away the used cups, do not pour the liquid back into the bottle!
• Preferably, never touch the electrode, certainly not with your fingers. If you want to clean it, only use a soft cloth without rubbing the electrode.

What is pH?

pH measures the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids with a larger concentration of hydrogen ions than water are acid and have a pH value less than 7. On the other hand, liquids with a lower concentration of hydrogen ions are base and have a pH value higher than 7. The pH scale runs from 1 to 14.
