How to choose laboratory dissolved oxygen meter

Dissolved oxygen meter is an analytical instrument specially used to measure the dissolved oxygen concentration in water. According to the method of use, there are pen type, portable, desktop and industrial online dissolved oxygen analyzers. Portable and desktop dissolved oxygen meters are commonly used in laboratories.

Key factors for choosing water dissolved oxygen meter

1. Basic functions

Dissolved oxygen concentration measurement, dissolved oxygen saturation and temperature measurement are the basic functions of the dissolved oxygen meter.

2. Advanced functions

Some advanced functions can greatly improve work efficiency, such as automatic temperature compensation function, calibration function, standard solution alarm function, data management and storage, electrode management, communication interface, etc.

3. Accuracy and stability

Investigate whether the nominal accuracy range of the instrument meets the measurement requirements, whether the analysis speed is fast enough, how anti-interference is, and whether the test results are repeatable.

4. Waterproof and dustproof

The dissolved oxygen do meter with waterproof and dustproof function is suitable for outdoor operations. Generally speaking, the dissolved oxygen meter with the protection level of IP65 can meet the needs of most outdoor operations.

5. Self-protection

See if the instrument has a data power-off protection mode, and whether it has power management functions such as automatic shutdown.

6. Type selection

Pen type, portable, desktop or industrial dissolved oxygen meter is mainly based on the usage scenario.Portable dissolved oxygen meter is suitable for the working environment which is not fixed. Benchtop dissolved oxygen meters are most commonly used in laboratories. Industrial dissolved oxygen meters are generally used in industrial production.
