D200 online ORP electrode

Activation:If the electrode is stored in a dry environment, it must be soaked for 24 hours before use to activate it, otherwise calibration and measurement will result in significant errors.
clean:When the electrode is found to be contaminated or blocked, affecting the measurement accuracy, a soft brush can be used to gently brush the electrode head, and then clean it with clean water. The cleaning methods for various types of pollution are as follows: oil or oily substances can be cleaned with surfactants; Calcium precipitates or metal hydroxides can be cleaned with 10% dilute hydrochloric acid; For sulfide precipitation (such as during wastewater treatment), a mixture of 10% dilute hydrochloric acid and saturated thiourea can be used for cleaning; Protein attachments can be cleaned with a mixture of 10% dilute hydrochloric acid and pepsin.
Regeneration:When the electrode response becomes slow and almost sluggish, soak it in a mixture of 10% HNO3 and NH4F (50g/l) for regeneration. Usually within ten seconds

Standard configuration: Comes with a 10 meter ORP electrode dedicated cable (cable can be customized, customers cannot cut or extend it without authorization)

The quality of ORP meter usage largely depends on the maintenance of the electrodes. The electrodes should be cleaned regularly to ensure that they are not contaminated or blocked; Calibrate the electrodes periodically; During the water outage, it is necessary to ensure that the electrodes are immersed in the tested liquid, otherwise their lifespan will be shortened; The cable connectors must be kept clean and free from moisture or water ingress.
