Wireless pH Electrode

This Wireless pH Electrode is a general-purpose plastic bodied, single junction gel filled glass electrode, which is non-refillable. This electrode uses a direct to BNC connector. Suitable for use with both the Wireless pH Adaptor and the SmartQ pH Adaptor.
This Wireless pH Electrode is supplied with a pH storage bottle containing storage solution. Maintain the level of storage solution, the pH sensitive glass membrane must be kept wet. Store the electrode tip in a 1:1 solution of pH 4 buffer and 3.5 to 4 mol dm^-3 KCl. Do not ever store in de-ionised or distilled water as this will cause the migration of the electrode's fill solution.
To maximise electrode life, avoid pH/ temperature extremes whenever possible. High temperature, strong acids or caustics (greater than 1.0 mol dm-3 ) shorten electrode life. If used at high temperatures, the electrodes life is drastically reduced. The higher the range of temperature, the shorter the life of the electrode e.
g. typical electrode life when used at ambient temperature is 1 3 years, if used at 80C this will be reduced to less than 4 months.Practical Teaching

When used in conjunction with a suitable pH adaptor (SER3125 or DATH1110) , the following typical experiments can be achieved:

• Testing acids and alkalis
• Acid-base titrations
• Dissolved Oxygen in water
• Enzyme action
• Human or Cell respiration
• Monitoring photosynthesis
• Fermentation
• Monitoring pH change during a chemical reaction
• Water quality
