Quality ph meter digital installation and maintenance related matters

There are two types of installation methods for quality ph meter digital: flow-through and immersion.

The sewage treatment plant generally chooses the immersion installation. For example, the quality ph meter digital of the sewage treatment plant is installed in the outlet overflow tank of the grit chamber. The meter digital doesn't cause a big shock. Regular maintenance helps the meter to measure accurately and extend the life of the meter. It should be noted that the special cable between the sensor and the transmitter cannot get wet, 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. Every month or so, the electrode should be cleaned. First, spray the attachment with a gentle water flow, then soak the electrode in the cleaning solution for a period of time, and then wash it with clean water.

The quality ph meter digital sensor holder should also be cleaned. After each cleaning, a buffer solution should be used for calibration. The manufacturer generally provides two bottles of standard solution, one with a pH value of 7, which is used to calibrate the zero point of the instrument; one bottle with a pH value of 4, which is used to calibrate the signal output slope of the instrument. .
