Dissolved Oxygen Meter,Portable Oxygen Meter Range:0-40mg/L,Dissolved Oxygen Test Kit with Electrode Filling Fluid,Aquarium Water Test Kit

  • The oxygen meter is used to measure the dissolved oxygen content in aqueous solution, and the dissolved oxygen concentration is usually expressed in mg/L (dissolved oxygen per liter of water) or ppm (one millionth).Dissolved oxygen test kit on the market is 0.0-20mg/L,but our dissolved oxygen meter can test the value for 0.0- 40.0mg/L..
  • Proper dissolved oxygen is essential for good water quality and all life forms require oxygen.If the oxygen monitor content in the water is lower than 5.0mg/L, it will be difficult for aquatic organisms to survive, and the lower the concentration, the more difficult it will be. If the oxygen meter content is lower than 1-2mg/L and lasts for several hours,it will lead to the death of a large number of aquatic organisms.So dissolved oxygen meter is very important for aquaculture,biological reactions,ponds..
  • ‍♂️Dissolved oxygen meter can be used to measure and monitor processes where oxygen levels can affect reaction rates, process efficiency or the environment:e.g.aquariums,swimming pools,teaching experiments, laboratory sterile environments,scientific research,environmental testing (lakes, streams, oceans),Wastewater treatm....
