Product introduction
The online fluorescence dissolved oxygen detector is an online
intelligent dissolved oxygen detector produced by our company.The
dissolved oxygen is measured by fluorescence method, and the
emitted blue light is irradiated on the fluorescent layer. The
fluorescent substance is excited to emit red light and oxygen. The
concentration is inversely proportional to the time at which the
fluorescent material returns to the ground state. A reference red light is also set up, and the concentration of
oxygen molecules is calculated by measuring the phase difference
between the excitation red light and the reference red light and
corresponding to the internal calibration value. The use of this advanced analytical technology ensures that the
instrument is stable, reliable and accurate over the long term. It
has English menu operation, also can be widely used in chemical
fertilizer, metallurgy, environmental water treatment engineering,
pharmaceutical, biochemical, food, aquaculture and tap water and
other solutions in the continuous monitoring of dissolved oxygen
values.

nstrument installation
Host installation
The instrument should be installed in a clean, dry, well-ventilated
location without vibration, and there should be no corrosive gas
around it.
The installation method is wall-mounted installation. First, fix
the screws on the wall according to the position of the
installation hole of the instrument, and then install it firmly.
Installation of Sensor
Do not put the electrode directly into the water. Installing the
electrode into a bracket or flow cup. Before installation, please
make sure to use the PTFE tape (3/4 thread) to do the waterproof
sealing work to avoid water entering the electrode and then causing
short circuit of the DO electrode cable.
