Hapnikumõõtur

Hapnikumõõtur is an Estonian term that translates to "oxygen meter" in English. It refers to a device used to measure the concentration of oxygen in a given environment or substance. These devices are crucial in various fields, from medical applications to environmental monitoring and industrial processes.

In a medical context, an oxygen meter, often referred to as an oximeter when used for blood oxygen saturation, is vital for assessing a patient's respiratory function. It can help diagnose conditions like hypoxia, where the body's tissues are not receiving enough oxygen, and monitor the effectiveness of oxygen therapy. These medical devices typically use light absorption to determine oxygen saturation in the blood.

Beyond healthcare, oxygen meters are employed in environmental science to assess air quality and water oxygen levels. Aquatic oxygen meters, for instance, are essential for understanding the health of water bodies and supporting aquatic life. In industrial settings, oxygen meters are used to ensure safety, such as in mines where oxygen depletion can be a hazard, or to control processes that require specific oxygen concentrations, like combustion.

The principle behind many oxygen meters involves electrochemical sensors that react with oxygen, generating an electrical signal proportional to the oxygen concentration. Other types utilize optical methods. The accuracy and range of these meters vary depending on their design and intended application, making them versatile tools for a wide array of measurement needs.
