Oxygen meters
At PCE-Group you will find diverse oxygen meters for water. There are available oxygen meters for both pure oxygen content and for oxygen concentration. Oxygen meters have a water resistant design, interface and internal data memory as well as the classical version for laboratories. Most of our oxygen meters are hand devices due to the fact that they are the most demanding chemical instruments for water analysis with a high accuracy and easy to use. Calibration of oxygen meters for water is very easy to perform (manual two-points calibration or automatic calibration), therefore even inexperienced customer can calibrate the instrument. Any of our oxygen meters can perform measurements depending on every industrial feel independently the technical problem. If you don't find the oxygen meters you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 ( 0 ) 191 377 3398 and our technical staff will advise you regarding our  measuring instruments  .

Oxygen in water: Oxygen content in water is the concentration of oxygen dissolved in water. Most of the bodies need a minimum concentration of oxygen dissolved in water to survive. The oxygen dissolution in water depends on both the temperature and the content of dissolved substances. A rising temperature causes a better dissolution. The saturation value at 0ºC is 14,6 mg O₂/l and at 20 º is 9,1 mg O₂/l. The critical concentration in fish farming is under 4 mg O₂. The content of oxygen in water is the result of the input and consumption of oxygen. Oxygen comes from the atmosphere, it is important to bear in mind that the amount of oxygen will depend on the water surface, water temperature, saturation deficit, water turbulence and the air movement. Apart from their use in the industry, these oxygen meters are also important in the agriculture, horticulture and gardening. Oxygen is also released during photosynthesis in plants. On the other hand, oxygen is consumed during the natural decomposition of organic substances in water by means of the micro organisms activity, as well as the animals and plants breathing. This fact can lead to a oxygen deficiency in water. Oxygen meters are also used in laboratories to discover a product properties when the are irrigated with different oxygen content in water so as to maximize the product properties. So, as you can understand, the use of oxygen meters is very important in many diverse sectors.
