Dissolved oxygen (DO) in water is measured using several types of sensors, each based on a different principle. The main types are:

1. Optical (Luminescent / Fluorescence Quenching) DO Sensors

Based on the principle that dissolved oxygen quenches (reduces) the fluorescence of a dye. A blue or UV LED excites a luminescent dye; the presence of oxygen changes the fluorescence intensity or lifetime.

OPS Optical DO Sensors

Pros:

No oxygen consumption (suitable for stagnant samples).

Low maintenance and long calibration stability.

Rapid response, good for long-term monitoring.

Cons:

More expensive than electrochemical sensors.

2. Electrochemical Sensors

These measure oxygen using an electrochemical reaction at an electrode.

a. Polarographic (Clark-type) sensors

Use a membrane-covered cathode and anode with an applied voltage.

Oxygen diffuses through the membrane and is reduced at the cathode, producing a current proportional to DO.

Pros: Inexpensive, well-established.

Cons: Requires polarization time and regular calibration; consumes oxygen (can affect readings in stagnant water).

b. Galvanic sensors

Similar to polarographic, but they generate their voltage (no external power needed).

Pros: Faster start-up, low maintenance, no polarization time.

Cons: Still consumes oxygen and requires regular membrane/electrolyte replacement.

3. Winkler Titration (Classical Method)

A chemical (wet lab) method, not a sensor.

Involves adding reagents (manganese sulfate and alkali iodide-azide) to fix oxygen, then titrating with sodium thiosulfate.

Pros: Highly accurate, used for calibration.

Cons: Labor-intensive, not real-time, and requires specialized skills.

In practice:

Optical DO sensors are increasingly popular for long-term environmental monitoring due to their low maintenance needs.

Polarographic and galvanic sensors are common in field probes and portable meters.

Winkler titration is often used as a reference or for calibrating other sensors.

Dissolved Oxygen (DO) sensors are devices used to measure the concentration of oxygen dissolved in water. This parameter is crucial for assessing water quality, as it directly affects the survival and health of aquatic organisms. DO sensors are widely used in various applications, including environmental monitoring, aquaculture, wastewater treatment, and scientific research.

There are different types of DO sensors available, each utilizing different principles to measure dissolved oxygen. The two most common types are:

Optical DO Sensors:

    These sensors use an optical method to measure dissolved oxygen. They typically consist of a probe with a luminescent material that emits light when exposed to a specific wavelength. The intensity of the emitted light is inversely proportional to the concentration of dissolved oxygen in the water. By measuring the light intensity, the sensor can determine the DO concentration.

    Dissolved Oxygen DO sensors

    Electrochemical DO Sensors:

    These sensors use an electrochemical cell to measure dissolved oxygen. They usually consist of two electrodes—an anode and a cathode—immersed in an electrolyte solution. The oxygen molecules diffuse through a gas-permeable membrane and are reduced at the cathode, generating a current that is proportional to the DO concentration.

    Both types of DO sensors require regular calibration to ensure accurate measurements. Calibration involves exposing the sensor to known dissolved oxygen concentration and adjusting the sensor readings accordingly.

    DO sensors can be integrated into water quality monitoring systems or standalone handheld devices. They provide real-time data on dissolved oxygen levels, allowing for timely action if oxygen depletion occurs. This information is crucial for maintaining healthy aquatic ecosystems, optimizing fish farming conditions, and ensuring the effectiveness of wastewater treatment processes.

    Installation method of fluorescent dissolved oxygen sensor

    The equipment adopts an immersion installation method, which is a fixed installation immersed below the liquid surface. Avoid bumping and scratching the surface of the fluorescent membrane head during installation and use. The fluorescent membrane head should be protected from underwater sediments. The rubber protective cover should be removed during use. The sensor thread can be customized based on the thread of the waterproof pipe.

    The basic principle of fluorescent dissolved oxygen sensor

    The sensor mainly uses the principle of fluorescence quenching. Blue light irradiates the fluorescent material to excite the fluorescent material and emit red light. Since oxygen molecules can take away energy (quenching effect), the time and intensity of the red light excitation 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 it with the internal calibration value, the concentration of oxygen molecules can be calculated.

    fluorescent dissolved oxygen sensors

    Comparative advantages of fluorescent dissolved oxygen sensors:

    1. No oxygen consumption

    This type of equipment does not consume oxygen, has no flow and stirring requirements, and can better meet the needs of oxygen measurement.

    2. High-precision probe

    The device has higher resolution and measurement accuracy, and the measurement is fast and sensitive.

    3. Wide-voltage power supply

    The equipment uses a wide voltage power supply, can use DC6~24V, and can adapt to various DC power supplies on site.

    4. RS485 communication interface

    The equipment uses MODBUS RTU communication protocol, which can be easily connected to a computer for monitoring and communication.

    5. Temperature compensation

    The equipment has a built-in temperature transmitter with an automatic temperature compensation function, which can reduce measurement errors and improve accuracy.

    6. Long-term maintenance-free

    The equipment does not need to replace the diaphragm and electrolyte, is maintenance-free, and has a longer service life.

    7. High-protection shell

    Conventional freshwater aquaculture can use SS316 shell.

    For saltwater or seawater aquaculture, a highly protective and corrosion-resistant shell is used, with a waterproof grade of IP68, which is more stable; all sensors use titanium alloy shells, which are resistant to salt and alkali corrosion for a long time.

    During the breeding process, due to climate change or water quality deterioration, the dissolved oxygen in the water is low. At this time, the breeders need to supplement oxygen. In the past, breeding was based on experience. The staff needed to patrol the pond three times a day. When to add oxygen? How much? It can only be done by “estimation”. If the adjustment is inaccurate, it will affect the growth of aquatic animals. Nowadays, the aquaculture industry is in the stage of transformation and upgrading, and the use of scientific and technological forces for intelligent breeding is becoming a mainstream trend.

    Xi’an OPS Electronic Technology Co., Ltd’s dissolved oxygen sensor uses the principle of fluorescence measurement to monitor the dissolved oxygen concentration signal of each breeding pond in real-time, which is scientific, accurate, and economical. It saves time and effort and facilitates the breeders to understand the pond situation in real-time and take corresponding measures in time to achieve the effect of intelligent breeding. It can be widely used in water treatment, aquaculture, biological response, environmental monitoring, laboratory, medical, and many other fields.

    The application of fluorescent dissolved oxygen sensors can help farmers scientifically “do a good job” of dissolved oxygen, ensure a good water quality environment, and take an important step in “raising water”, avoiding the traditional empirical theory of regulating water quality, and achieving efficient management and increased production. The value-added effect is more in line with the general trend of intelligent transformation of aquaculture.

    Fluorescent dissolved oxygen probes have become the mainstream trend, gradually replacing electrochemical dissolved oxygen probes.

    As the key instrument for monitoring dissolved oxygen in aquaculture water, the dissolved oxygen probe provides essential data that is most frequently referenced in production. Its measurement accuracy is critical. Inaccurate monitoring data lacks value and may lead to production losses. Considering the specific environmental characteristics of aquaculture water and the decreasing cost of the new generation of fluorescent dissolved oxygen probes, the existing electrochemical dissolved oxygen probes in the market are increasingly losing their relevance and market share compared to these new probes.

    Fluorescent Dissolved Oxygen Probes

    Comparison of the new generation of fluorescent dissolved oxygen probes versus electrochemical dissolved oxygen probes:

    Routine Maintenance Comparison:

    Electrochemical Method: This method requires adding electrolytes every 1-2 months, regular replacement of membrane heads, and calibration. It involves significant and cumbersome maintenance.

    Fluorescent Method: Almost maintenance-free, typically only requiring the replacement of the fluorescent membrane every 2-3 years.

    Interference Resistance Comparison:

    Electrochemical Probe: The measurement results are affected by water flow, with weak resistance to interference. It is easily influenced by various chemical substances in the water, such as heavy metal ions, H₂S, and NH₄.

    Fluorescent Probe: The measurement results are not affected by water flow and have strong resistance to interference, with little to no impact from other factors, making it highly interference-resistant.

    In actual production, aquaculture water environments tend to be eutrophic, which requires frequent cleaning of the probes. Given the complicated maintenance of electrochemical probes, many aquaculture operators do not adhere to proper cleaning and calibration procedures. Combined with the high level of interference, this often results in inaccurate measurements, posing production risks. With the decreasing price of fluorescent dissolved oxygen probes, their adoption has become inevitable.
