Chapter 1 Introduction
Dissolved oxygen online controller, is widely applied for continuous monitoring and
measurement of dissolved oxygen, saturation, oxygen partial pressure and
temperature in the solution in the industry of thermal power, chemical fertilizer,
environmental protection, metallurgy, pharmacy, biochemistry, food and water, etc.
Continuous monitoring measurement data is connected with the recorder via
transmitting output to realize remote monitoring and recording. It can also be
connected with RS485 portal via MODBUS-RTU protocol to access computer for
monitoring and recording.
