Automatic Potential Titrator consists of two parts, the electrometer and the titration system. The electrometer uses an electronic amplification control circuit to compare the potential between the indicator electrode and the reference electrode with a preset end point potential.
Automatic Potential Titrator is a common analytical instrument designed for capacity analysis based on the principle of potentiometric method.
Liquid electrodes such as InPro2000 series are refillable liquid electrodes. This electrode is the electrode with the most classic design, the best quality, and the widest range of applications in the history of pH electrode invention.
In some water bodies, the dissolved oxygen content in the water will increase significantly due to some reasons, leading to rich oxidation in the water body, and the dissolved oxygen content can reach more than 20mg/L.
The national standard HJ 802-2016 "Electrode Method for the Determination of Soil Electrical Conductivity" gives a method for the determination of soil electrical conductivity.
