The Dissolved Oxygen Meter accurately measures dissolved oxygen and temperature in a variety of environments, including aquariums, swimming pools, ponds, and aquaculture, and it accurately measures the concentration of oxygen in the water with a resolution of 0.1 mg/L, 0.1%.

Typically, the minimum amount of dissolved oxygen that supports a large number of different fish species is 4 to 5 mg/L. At dissolved oxygen levels of 5 mg/L or more, fish feeding is normal; when dissolved oxygen levels drop to 4 mg/L, fish feeding decreases by 13%;

Application：Widely used in: fish tanks, aquariums, koi ponds, marine aquaculture, freshwater aquaculture, swimming pools, domestic water, hydroponics, etc.
