Features and Applications:

&NBSP uses a built-in microcomputer to store, calculate, and compensate for the temperature characteristics of pH electrodes, the slope of pH/ORP electrodes, and zero potential deviation. The software features rich design, stable memory, and operational protectionThe automatic and manual three-point calibration allows for the selection of pH upper and lower limit alarms. The dual relay control output has extremely high input impedance and is compatible with various types of pH electrodes, quantitative dosing, and stirring devices to achieve automatic control of liquid acidity and alkalinity.
&nbsp&nbsp&nbsp&nbspWidely used for monitoring and adjusting acidity and alkalinity in water treatment processes, continuous monitoring of environmental engineering and industrial wastewater treatment processes, analysis and control of water quality acidity and alkalinity in factories, school physical and chemical laboratories, and various industries.
