pH probe should be put horizontally or vertically?

pH meter is an instrument that is widely used in laboratories and industrial production to measure the acidity and alkalinity of a solution. It is widely applied in the fields of industry, electricity, agriculture, medicine, food, scientific research and environmental protection, and is also an essential inspection equipment for food factories and drinking water plants.

The pH probe should be placed vertically. The pH tester is used to detect the pH value of the liquid in the pipeline in real time, so the pH probe must be placed vertically to observe the data in real time. If it is installed horizontally at the bottom of the pipeline, the data cannot be seen. If it is installed at the upper part of the pipeline, the pH meter does not contact with the liquid and cannot obtain real data.

The pH detector consists of a sensor and a secondary meter. It can be equipped with three or two composite electrodes to meet various usage scenarios. With pure water and ultrapure water electrodes, it can be used to measure the pH value of water with a conductivity of less than 3μs/cm.
