DO Meter Calibration

A dissolved oxygen meter is a water quality measuring device that measures the amount of dissolved oxygen in water. The device is also known as a DO meter. Oxygen meters have many different models and designs, serving the maximum needs of people.

A dissolved oxygen meter is a device that measures the amount of dissolved oxygen in water and is also known as a DO meter. It is used to determine the quality of water by measuring the amount of gaseous oxygen present in it. There are many different models and designs of DO meters available, each with its unique features and capabilities, to meet the specific needs of different users.

DO meters can be classified into two types: optical meters and conventional meters. Optical meters use an optical system to perform measurements, while conventional meters use an electrode system to measure. Both types of meters have their advantages and disadvantages, and the choice of meter depends on the specific application and user requirements.

The structure of a DO meter may vary depending on different models and designs. However, DO meters usually include the following main parts:

• Machine case: This is the part that covers and protects the machine, and determines the shape to help users distinguish between different brands and models.
• DO measuring part: In optical measuring machines, it will be an optical system, while in conventional machines, people use a DO measuring probe.
• Electronic circuit board: This is the place to receive and process information from the user through the function keys, from the sample through the measuring part, then encode and transmit it to and display it on the screen.
• Function keys: These are the parts that receive user information and transmit it to the electronic circuit to set up and control the machine.
• Screen: This is where information is displayed to help users perform operations and read results more easily.
