Dissolved oxygen analyzer is a professional instrument used to measure the dissolved oxygen content in water, widely used in environmental monitoring, aquaculture, sewage treatment, water quality analysis and other fields. Its main characteristics can be reflected from multiple dimensions such as measurement performance, functional design, and applicable scenarios, as follows:

1、 High precision measurement capability

·high accuracyThe sensor technology used, such as polarography and fluorescence, can quickly and accurately detect the concentration of dissolved oxygen in water, and the measurement error can usually be controlled within ±0.1 mg/LWithin, meet the high-precision monitoring requirements.

·Fast response speedAfter the sensor comes into contact with the water sample, it can complete readings within seconds to tens of seconds, suitable for real-time monitoring or dynamic changes in water environments (such as dissolved oxygen fluctuations during water exchange in aquaculture ponds).

2、 Multi parameter compatibility and expansion

·Dissolved oxygen as the main factor, taking into account other factorsPartial dissolved oxygen meters can simultaneously measure water temperature, salinitypHValue and other parameters. For example, salinity can affect the solubility of dissolved oxygen, and the instrument can automatically calibrate the dissolved oxygen results based on salinity values, improving measurement accuracy in complex water bodies.

·Adjustable range: Supports measurement of dissolved oxygen concentration in different ranges, with common ranges being0-20 mg/L(or0-200%Air saturation can adapt to various scenarios ranging from low oxygen (such as sewage) to high oxygen (such as oxygen rich water bodies).

3、 Design that adapts to complex environments

·Strong anti-interference abilityThe sensor is made of special materials such as platinum electrodes and fluorescent caps, which can reduce the interference of impurities, chemicals (such as chlorine gas), or biological attachments in water and extend its service life.

·Waterproof and durabilityThe body usually hasIP67Waterproof rating above, can be directly immersed in water for operation (some portable models), or withstand humid and harsh on-site environments (such as sewage treatment plants).

4、 Convenient operation and intelligence

·Automatic calibration functionSupport air calibration (using known oxygen content in the air) or standard solution calibration, complete the calibration process with one click, and reduce human operation errors.

·Data storage and exportBuilt in memory can record thousands of sets of measurement data (including time and parameter values), supported by some modelsUSBExport data through Bluetooth and other methods to facilitate subsequent analysis (such as generating water quality reports).

·Visual display: Large screenLCDorOLEDThe display screen can clearly show information such as dissolved oxygen value, temperature, battery status, etc. Some models support backlighting and are suitable for operation in dim environments.

5、 Diversified model selection

·portableSmall in size and lightweight, equipped with a carrying case or portable design, suitable for field testing (such as river and lake sampling).

·desktopHigher accuracy and stronger stability, suitable for laboratory high-precision analysis or long-term continuous monitoring.

·onlineCan be fixedly installed in water bodies (such as aquaculture ponds and pipelines), real-time monitoring and remote feedback of dissolved oxygen values through data transmission systems, supports over limit alarms (such as sound and light alarms), and facilitates timely regulation (such as automatic activation of oxygenation equipment).

6、 Widely applicable adaptability

·Aquaculture: Real time monitoring of dissolved oxygen content in the growth environment of fish and shrimp to avoid death caused by hypoxia.

·Environmental monitoring: Evaluate the ecological health of rivers and lakes (dissolved oxygen is an important indicator of water self purification capacity).

·Wastewater treatment: Monitor the dissolved oxygen level in the aeration tank, optimize the operating efficiency of aeration equipment, and reduce energy consumption.

·In the industrial field, such as drinking water treatment, beer brewing, etc., ensure that the water quality meets the process standards during the production process.

In short, the core feature of the dissolved oxygen analyzer isHigh precision, high adaptability, and convenient operationIt is an essential tool in water quality analysis and environmental management, designed with diverse functions to meet the monitoring needs of dissolved oxygen in different scenarios.
