Product Description
Online Fluorescence Dissolved Oxygen Sensor High Accuracy dissolved oxygen meter



Brief introduction


The DS380 series of fluorescent dissolved oxygen sensors uses a new type of fluorescence lifetime technology and high performance fluorescent materials.



-Best-in-class fluorescence lifetime technology and high performance fluorescent materials.

-No oxygen consumption, no flow rate restrictions, no electrolyte, no maintenance and calibration required, no hydrogen sulphide interference, excellent stability.

-Built-in temperature sensor with automatic temperature compensation.

-RS485 output for networking without controller.

Characteristics
1.Hydrophobic membrane, algae will not stick to the membrane head
2.Digital sensor, RS485 output, MODBUS support
3.Membrane-free, electrolyte-free, interference-free, no need for frequent calibration
4.No oxygen depletion, no flow limitation
5.Built-in temperature sensor, automatic temperature compensation
