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. 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 and notebook to store measurement data. 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.
The product has high precision, high stability and strong anti-interference and anti-pollution ability, durable.
No oxygen consumption is generated during the measurement, and there is no excessive requirement for the flow rate.
New waterproof, dust proof, moisture-proof and high quality shell (IP65) technology, surface spray paint technology, instrument appearance generous, high-end.
With automatic cleaning function, the cleaning device (optional) is the tap water cleaning method.
Multi-parameters display simultaneously:Dissolved oxygen value, temperature, output current, Alarm pointetc. are displayed at the same time, which is intuitive and easy to read, and has a range over limit prompt.
The screen displays the alarm status and can be accompanied by the switch ON/OFF signal output.
Automatic temperature compensationfunction:0-60℃
The DO value corresponding to the 4~20 mA current output can be set arbitrarily
Notepad: can store 50 Measured data．users can record the measurement data as needed.
The hysteresis amount can be set arbitrarily to avoid frequent switching of the switching relay.
Watchdog function: make sure the meter doesn't crash.
Control interface: two sets of ON / OFF relay contacts are divided into upper and lower limit alarm signal photoelectric isolation output. The third group of relays: automatic cleaning control function analog output
