Hapnikumõõtjad

Hapnikumõõtjad, also known as oxygen meters or oximeters, are devices used to measure the concentration of oxygen in a gas or liquid. In medical contexts, pulse oximeters are commonly used to measure the oxygen saturation level in a person's blood. These non-invasive devices typically clip onto a fingertip, earlobe, or toe and use beams of light to determine how much oxygen is bound to hemoglobin in the red blood cells. The results are displayed as a percentage, indicating the proportion of hemoglobin that is carrying oxygen.

Beyond medical applications, hapnikumõõtjad find use in various industries. They are employed in environmental monitoring to assess oxygen levels in aquatic environments, which can be crucial indicators of water quality and ecosystem health. In industrial settings, such as welding or diving, these meters are vital for ensuring a safe atmosphere by monitoring oxygen concentrations and preventing potential hazards like oxygen deficiency or enrichment. Some hapnikumõõtjad are designed for continuous monitoring, providing real-time data, while others are portable for spot checks. The technology behind them often involves electrochemical sensors or optical methods, depending on the specific application and the medium being measured.
