Aquaculture water quality monitoring online dissolved oxygen sensor
Fluorescence dissolved oxygen sensor
The DS380 series of fluorescent dissolved oxygen sensors use a new generation of fluorescence lifetime technology and high performance fluorescent materials. No oxygen consumption,o flow rate limitation, no electrolyte, no maintenance and calibration,no interference from hydrogen sulfide, excellent stability. Built-in temperature sensor, automatic temperature compensation. RS485 output, can be networked without a controller. 

* Digital sensor, RS485 output, support MODBUS * There is no electrolyte, no interference, no need for frequent calibration * No oxygen consumption, no flow rate limit * Built-in temperature sensor, automatic temperature compensation
