Dissolved Oxygen Meter & Analyser Suppliers

Is a device used to measure the amount of oxygen dissolved in a liquid, typically water. It is commonly used in environmental monitoring, wastewater treatment, and aquaculture. The meter typically consists of a probe or sensor that is inserted into the liquid, and a display unit that shows the dissolved oxygen level in parts per million (ppm) or milligrams per liter (mg/L). The analyser can also provide additional data such as temperature, pH, and conductivity. Accurate measurement of dissolved oxygen is important for maintaining healthy aquatic environments and ensuring effective wastewater treatment.

Dissolved Oxygen Meters and Analysers are devices used to measure the amount of dissolved oxygen in a liquid. There are different types of Dissolved Oxygen Meters and Analysers available in the market, which can be classified based on their working principle, type of sensor, and application.

• Electrochemical Dissolved Oxygen Meters: These types of meters use an electrochemical sensor to measure the amount of oxygen in the liquid. They are accurate, easy to use, and can measure dissolved oxygen levels in a wide range of applications.
• Optical Dissolved Oxygen Meters: These meters use a luminescent sensor to measure the amount of dissolved oxygen in the liquid. They are more expensive than electrochemical meters but are more accurate and can provide real-time readings.
• Polarographic Dissolved Oxygen Meters: These meters use a polarographic sensor to measure the amount of oxygen in the liquid. They are commonly used in wastewater treatment plants and are less expensive than optical meters.
• Clark-Type Dissolved Oxygen Meters: These meters use a Clark-type sensor to measure the amount of dissolved oxygen in the liquid. They are commonly used in research laboratories and are more expensive than other types of dissolved oxygen meters.
• Portable Dissolved Oxygen Meters: These meters are small, handheld devices that are commonly used in field applications. They can be either electrochemical or optical and are ideal for measuring dissolved oxygen levels in lakes, rivers, and other bodies of water.
• Online Dissolved Oxygen Analysers: These analysers are designed to continuously measure the amount of dissolved oxygen in a liquid. They are commonly used in wastewater treatment plants, food and beverage production, and other industrial applications.

In conclusion, the type of dissolved oxygen meter or analyser you choose will depend on your specific application and requirements. It is important to consider factors such as accuracy, cost, and ease of use before making a decision.

Dissolved oxygen meters and analyzers are generally accurate, but their accuracy depends on various factors. The accuracy of a dissolved oxygen meter or analyzer depends on its calibration, temperature compensation, and other factors. If the meter is calibrated correctly, it can provide accurate measurements of dissolved oxygen levels in water. However, if the meter is not calibrated or calibrated incorrectly, it can provide inaccurate results. Temperature compensation is also essential for accurate measurements, as dissolved oxygen levels vary with temperature. Therefore, dissolved oxygen meters and analyzers need to be calibrated and temperature compensated regularly to ensure accurate results. Overall, dissolved oxygen meters and analyzers are reliable tools for measuring dissolved oxygen levels in water, but their accuracy depends on proper calibration and temperature compensation.

The accuracy of Dissolved Oxygen Meters & Analysers can be affected by several factors, including temperature, salinity, pressure, pH, and calibration. Temperature has a significant impact on the solubility of oxygen in water, and a change in temperature can result in inaccurate readings. Salinity can also affect the solubility of oxygen in water, and water with high salinity levels can lead to lower dissolved oxygen readings. Pressure changes can affect the solubility of oxygen, and pH levels can affect the chemical reactions that measure oxygen. Finally, calibration is critical to ensuring accurate readings, and any errors in calibration can lead to inaccurate measurements.

Calibrating a dissolved oxygen meter and analyzer involves several steps:

• Prepare calibration solutions: Obtain two solutions—one with 100% saturation of dissolved oxygen and another with 0% saturation. These solutions should be at the same temperature as the samples you will be testing.
• Prepare the meter: Turn on the meter and let it warm up for at least 15 minutes. Then, ensure that the probe is clean and dry.
• Calibrate the meter: Immerse the probe in the 100% saturation solution and set the meter to read 100% saturation. Rinse the probe and immerse it in the 0% saturation solution and set the meter to read 0% saturation.
• Verify accuracy: Check the accuracy of the meter by measuring a sample with a known dissolved oxygen concentration. The reading should be within the manufacturer's specified range.
• Record calibration: Record the calibration values in a logbook or on the instrument's internal memory.
• Maintenance: Regularly clean and maintain the probe according to the manufacturer's instructions to ensure accurate readings.

By following these steps, you can ensure that your dissolved oxygen meter and analyzer are properly calibrated for accurate readings of dissolved oxygen concentrations in your samples.

The ideal range of dissolved oxygen that should be maintained in an aquarium or water body is between 5-7 mg/L (milligrams per liter). This range is suitable for most aquatic organisms and promotes their growth and survival. However, some species may require higher or lower levels of dissolved oxygen. A dissolved oxygen meter and analyzer can be used to measure and monitor the dissolved oxygen levels in the water to ensure they remain within the ideal range. This is important for maintaining a healthy and balanced ecosystem in the aquarium or water body.

Maintenance procedures for Dissolved Oxygen Meters and Analyzers include regular calibration, cleaning, and replacement of sensors and membranes. It is important to check the instrument's accuracy and sensitivity periodically and ensure that the electrodes are free from any debris or contaminants. The instrument should be stored in a dry and protected environment when not in use, and the batteries should be replaced regularly. It is also recommended to follow the manufacturer's instructions for maintenance and troubleshooting, and to seek professional help if necessary.

Are important tools for measuring the amount of oxygen present in water. When purchasing one, there are several features that you should look for, including:

• Accuracy: The accuracy of the dissolved oxygen meter is crucial to ensure that you get reliable readings. Choose a meter that has a high level of accuracy.
• Calibration: Some dissolved oxygen meters require frequent calibration. Look for a meter that is easy to calibrate and requires less frequent calibration.
• Temperature compensation: Dissolved oxygen meters are affected by temperature changes. A good meter should have a built-in temperature compensation feature to correct for temperature changes.
• Data storage: Look for a meter that can store data for later analysis. This will save you time and effort in recording readings manually.
• Durability: Choose a meter that is rugged and can withstand harsh environmental conditions. This is especially important if you will be using it in the field.
• User interface: The meter should have a user-friendly interface that is easy to operate. It should also have clear and easy-to-read displays.
• Battery life: Look for a meter with a long battery life to avoid frequent recharging or changing of batteries.

Connectivity: Some dissolved oxygen meters can connect to a computer or smartphone for data analysis. Look for a meter with this feature if you need to transfer data to a computer or smartphone.
