pH electrode for Astralpool Exactus dispensers

pH electrode for Exactus dosing pumps pH model of the prestigious brand Astralpool (also known as sensor or probe); measures and transmits the pH value of the water to the dosing pump.

It is important to mention that for a correct reading, it is very important to avoid the entry of air and place the measuring electrode in the flow line first and then the product injection connection.


This kit includes the following:

1. pH measuring electrode.
2. Buffer solutions as necessary for a correct calibration.
3. Collar.
4. level probe.
5. Electrode holder.
   
   
   
   

Manual


Electrode Preparation

Carefully remove the water cap. Wash the electrode with water.

pH: Check if there are air bubbles inside the glass membrane. Remove any bubbles by gently shaking the electrode vertically.


Electrode storage

The electrodes should be stored in the wash cap, which contains a 3M KCl solution or storage solution. Dry stored electrodes temporarily indicate unstable values. If the electrode has accidentally dried out, it can be regenerated by soaking it overnight in a storage solution.


Cleaning

Glass body electrodes can generally be cleaned with acids or bases (briefly) and with the usual solvents. Then rinse with water. After this, the electrodes probably indicate a slow response for a certain time; immerse the electrode in a storage solution for 15 min after cleaning.


Regeneration

pH: Immerse the electrode for 10 min in 0.1 - 1.0 M NaOH, then for 10 min in 0.1 - 1.0 M HCl. After regeneration, immerse it in storage solution for 15 min.


Elimination

These sensors have been designed to minimize their environmental impact. In accordance with the European directive EU 2002/96/EC, the sensors must be disposed of as waste electrical and electronic equipment, and not as household waste, or they can also be returned to the supplier for disposal.


General points

The life of the electrodes is strongly dependent on the customer's response, zero point and slope requirements. Measurement conditions especially high temperatures and aggressive samples can reduce the lifetime. Bass
Under favorable conditions, you can expect the electrodes to last 1 to 3 years at room temperature, and 1 to 3 months at 90°C. Slow aging also occurs during storage.
