Onrescence 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 sulde interference, exnt stability.
-Built-in temperature sensor with automatic temperature compensation.
-RS485 output for networking without controller.
Characteristics1.Hydrobic membrane, algae will not stick to the membrane head2.Digital sensor, RS485 output, MODBUS support3.Membrane-free, electrolyte-free, interference-free, no need for frequent calibration4.No oxygen depletion, no flow limitation5.Built-in temperature sensor, automatic temperature compensationTechnical Specifications
