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....
