KFDO600 Low Cost Good Quality Dissolved Oxygen Meter Water Quality
For Aquaculture 304 Stainless Steel Probe
Product Introduction
The fluorescence method dissolved oxygen measuring instrument is
based on fluorescence quenching principle.The fluorescent material
at the front of the sensor is a special platinum porphyrin compound
with a polyester foil that allows gas molecules to pass through.
The surface is coated with a black light-blocking material to avoid
interference by sunlight and other fluorescent substances in the
water.
When blue light hits the fluorescent material, the fluorescent
material is excited and emits red light. Since oxygen molecules can
carry away energy (quenching effect), the time and intensity of the
excited red light are inversely proportional to the concentration
of oxygen molecules.By measuring the phase difference between the
excitation red light and the reference light and comparing with the
internal calibration value, the concentration of oxygen molecules
can be calculated.After linearization and temperature compensation,
the final value is output.
Performance characteristics:
1. Principle of fluorescence quenching, no electrolyte digestion,
maintenance-free
2. No need to replace the fluorescent cap, the use cost is lower;
3. No oxygen consumption, no flow rate and agitation requirements
4. No interference from chemicals such as sulfides
5. High resolution and measurement accuracy
6. Chinese menu operation is simple, easy to operate and master
7. Special thickened cap film, not easy to wear, longer service
life
8. The unique protective cover design prevents irreversible damage
caused by the cap film hitting hard objects during the sensor reuse
process

Electrode installation
Electrodes are very delicate components and must be installed
correctly. The wrong installation can result in damage to the
electrodes or irreversible damage.The electrode is installed in
pipeline.Immersion. Both French and French installations are
available.
Do not put the electrode directly into the water. Instead, select
the electrode mounting bracket or the flow cup for fixation.Before
installation, please make sure to use the raw material belt (3/4
thread) to do waterproof sealing work, to avoid water entering into
the electrode and causing short circuit of the electrode cable.
During water outage, make sure that the electrode is immersed in
the tested liquid or wear the protective cap with the protective
liquid inside. If the temperature is low and the water is stopped
for a long time in winter, add antifreeze device or take back the
room to add water and store.Otherwise, the service life will be
shortened.

Q&A
What is zero drift?
It refers to the size of the indicating value of the automatic
analyzer changing within a certain period of time when the zero
correction liquid specified in this technical requirement is used
as the sample for continuous testing.
What is Range drift?
refers to the change of the indicating value of the automatic
analyzer in a certain period of time when the range correction
liquid specified in this technical requirement is used as the
sample for continuous testing.
What is Mean fail-free?
continuous running time refers to the ratio of the total running
time (h) of the automatic analyzer to the number of failures
(times) during the test period, which is shown in "MTBF". The unit
is h/time.
What is response time (T90)?
electrodes from range correction fluid to zero correction fluid,
the determination of displayed value range correction liquid
concentration 90%.
