KPH601 Online PH Sensor Signal Output: RS-485 (Modbus/RTU Protocol)

1.How to avoid contamination

• Periodic rinsing of the electrode with a suitable solvent.

• If the risk exists that solids may be deposited on the surface of the membrane they can be removed by increasing the stirring or flow velocity respectively.

The electrode should be cleaned when the junction or the glass membrane is contaminated. Depending on the type of contamination, different cleaning methods are recommended:

After these treatments the electrode has to be soaked in the reference electrolyte for 15 minutes. Also a recalibration has to be done before any new measurements can be carried out, since the cleaning solution diffuses into the junction during the cleaning procedure, and may cause diffusion potentials. The electrode should only be rinsed and never rubbed or otherwise mechanically cleaned, since this would lead to electrostatic charges. This could cause an increase in the response time.

2.Refill of electrolyte

The reference electrolyte has to be refilled or changed when: • the conducting element of the reference electrode is no longer completely immersed in the electrolyte (because of the diffusion of the electrolyte through the junction). • the reference electrolyte is contaminated (because of intrusion of the measuring solution). • the concentration of the reference electrolyte has increased through water evaporation.

Pressure compensation for liquid filled electrodes When measuring in a vessel or in a pipeline, the reference electrolyte is kept under a slight overpressure in order to avoid contamination by the measured solution. This procedure is only possible (and necessary) when using an electrode with a liquid electrolyte.
