Description

TECHNICAL FIELD

Mechanism sand requires professional equipment to produce qualified and applicable sand and gravel. In the production and application of mechanism sand, the use of flocculating agents is more common. However, excessive flocculating agents will adversely affect the performance of mechanism sand. Therefore, it is crucial to accurately detect the content of the flocculating agent in the mechanism sand. The content of the flocculating agent in the mechanism sand usually needs to be titrated by using a potential titrator.

[0003] The patent with publication number CN213715151U discloses an automatic potential titrator, which comprises a base, a potential titrator body arranged on the base, and a measuring mechanism arranged on the base.
