It is mainly used to stabilize the pH value of the solution in the production process, and realize automatic acid addition and alkali addition.

Description

• Mainly used for the stabilization of the pH value of the solution in the production process.

• Through RS485 communication (4-20mA analog signal), it can realize closed-loop control with peristaltic pump, so as to realize automatic addition of acid solution or Alkali to maintain the pH value of the solution.
