The online pH analyzer is an integrated design, using industrial online electrodes, digital and intelligent sensor design concepts. The instrument realizes functions such as electrode signal detection, temperature detection and automatic compensation, and digital signal conversion. RS485 signal output is convenient for network system integration and is not limited by transmission distance.
