An oxygen tester, also known as an oxygen sensor or oxygen meter, is a device used to measure the concentration of oxygen in a gas or liquid. Oxygen testers are used in a variety of settings, including industrial, medical, and scientific applications.
The most common type of oxygen tester is an electrochemical sensor that measures the oxygen concentration in a sample by measuring the electrical current produced by a chemical reaction between oxygen and a sensing electrode. The output of the sensor is typically displayed on a digital readout or transmitted to a computer or other data collection device.
Oxygen testers are used in a wide range of applications, such as:
Medical: Oxygen testers are used to monitor the oxygen levels in a patient’s blood or in medical gases used in respiratory therapy.
Industrial: Oxygen testers are used to monitor the oxygen levels in industrial processes, such as welding, where the concentration of oxygen can affect the quality of the weld.
Scientific: Oxygen testers are used in scientific research to measure the concentration of oxygen in air, water, or other samples.
Environmental: Oxygen testers are used to monitor the oxygen levels in aquatic environments, such as rivers, lakes, and oceans, to assess the health of aquatic organisms.
It is important to calibrate and maintain oxygen testers to ensure accurate and reliable measurements. Some oxygen testers may also require regular replacement of the sensing electrode or other components to maintain their accuracy and reliability.
