FAQ pH controller
1.How does the ph meter measure?
The online ph meter is composed of a controller and a ph electrode. The electrode gives an electric signal to the controller by sensing hydrogen ions in the solution. The ph value of the solution is obtained through an algorithm within the controller.
2.There are many ph types on the website. I don't know which one I should choose?
You can inform our engineers of the working conditions on site, such as the use situation, solution medium composition, solution pH range, solution temperature, etc. Our selection engineer will choose the appropriate electrode for you.
3.Can your ph meter be connected to PLC,DCS or computer on site?
Yes.Our ph controller supports 4-20ma output and can be connected to PLC or DCS.At the same time through the RS485 communication, connected to the computer for data processing.
4.Can your ph controller realize dosing control?
Of course,Our pH controller contains relay control, which can set the pH upper and lower alarm and control the solenoid valve switch, so as to realize dosing control.
