Applications：

Fluorescence industrial on-line dissolved oxygen

meter is a microprocessor based water quality on-line

monitoring and control instrument with .

The instrument equipped with fluorescent dissolved

oxygen electrode is widely used in power plants,

metallurgical electronics, mining, paper industry,

food and beverage,water treatment, aquaculture and

other industries;It continuously monitor and control

the dissolved oxygen and temperature value of water

solutions.

Feature：

●LCD screen, multi-line display

●Intelligent menu operation

●Data Recording & Curve Display

●Various automatic calibration functions

●Manual or automatic temperature compensation

●High alarm & low alarm,hysteresis control

●4-20mA&RS485Multiple output modes

●Dissolved oxygen, temp, etc.simultaneouslyshowed on the same screen

●Password protection function to preventmisoperation by non-staff.
