Fluorescence dissolved oxygen meter is an intelligent online optical analysis instrument, which is widely used in continuous monitoring of dissolved oxygen, saturation and temperature in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemicals, food and tap water.
The continuous monitoring data can be remotely monitored and recorded by connecting the recorder through the transmission output, and can also be connected to the RS485 interface through the Modbus-RTU protocol, which can be easily connected to the computer for monitoring and recording.
-The circuit design adopts modular design.
-Isolation transmission output is adopted, which is less affected by interference.
-Using isolated RS485 communication.
-It can measure dissolved oxygen, saturation and temperature.
-Air calibration can be performed.
-With automatic temperature compensation function.
-Has the function of setting high and low alarms and hysteresis.
-It has the function of setting buzzer and LCD backlight switch.
-Language can be selected, currently supports Chinese and English.
