How to install ph meter digital

There are two types of installation methods for ph meter digital: flow-through and immersion. Sewage treatment plants generally use immersion installation. Install the ph meter digital of the sewage treatment plant in the overflow tank at the outlet of the oxidation ditch, where the water flow is relatively stable and will not cause a big impact on the ph meter digital. The pH value measured from this is relatively stable and representative. In the process of installation and maintenance, it should be noted that the special cable between the sensor and the transmitter should not be damp, otherwise the high resistance and low voltage signal of the electrode will not be transmitted to the transmitter. If the electrode is not measuring, the yellow protective sleeve should be covered, which can keep the electrode in a wet state, which is beneficial to prolong the service life of the electrode.

In addition, it should also be noted that the electrodes should be cleaned regularly. First, spray the attachments with a gentle water flow, then soak the electrodes in the cleaning solution for a period of time, and then wash them with clean water. The ph meter digital sensor holder should also be cleaned. After each wash, calibrate with a buffer solution. The time interval is usually about a month.
