Selection knowledge of quality ph meter digital
Common quality ph meter digital, also called online acidity meter, is used to measure the content of hydrogen ions in the medium to judge the pH value of the measured solution. A set of common quality ph meter digital consists of three parts: transmitter, pH probe and probe mounting bracket. When we buy common quality ph meter digital, we need to fully understand the specific conditions of the site, so that we can choose a suitable common quality ph meter digital electrode and electrode mounting bracket.
We mainly need to know the following:
1. What is the medium? What is the temperature and pressure of the medium? Does it need to be preserved?
First of all, confirm the specific medium, as well as the working temperature and working pressure of the site, whether it is necessary to select a high-temperature electrode, and whether the electrode needs to be anti-corrosion? Use glass rod electrodes or plastic housing electrodes? You can also confirm the material of the sensitive film of the common quality ph meter digital electrode according to the medium.
2. What is the installation method of the electrode on site? Is there any reserved installation interface?
The installation method of quality ph meter digital on site, specifically whether it is pipeline installation or submerged installation, etc. If it is pipeline installation, it is recommended to use a simple sheath, and it can also be adapted to the corresponding material according to the reserved interface (such as flange, etc.). Mounting bracket or flow cell; if it is a submerged installation, it can be equipped with a submerged bracket or a floating plate bracket.
