Product details

Overview of Portable Fluorescence Dissolved Oxygen Sensor:
The HDO series portable fluorescence dissolved oxygen sensor adopts a new generation of fluorescence lifetime technology and uses independently developed high-performance fluorescent materials. No oxygen consumption, no flow rate limitation, no need for electrolyte, free from maintenance and calibration, not affected by hydrogen sulfide interference, with excellent stability. Built in temperature sensor with automatic temperature compensation.
Characteristics of HDO portable fluorescence dissolved oxygen sensor:
- Digital sensor, RS485 output, supports MODBUS
- No film, no electrolyte required, no interference, no need for frequent calibration
- No oxygen consumption, no flow rate limitation
- Built in temperature sensor, automatic temperature compensation
