Product Details
Online Fluorescence Dissolved Oxygen Sensor High Accuracy dissolved
oxygen sensor
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
