YFDGD Water Tester Digital DO9100 Dissolved Oxygen Meter Aquarium DO Tester Seawater Freshwater Fish Tank Aquaculture Water Quality Detector Multipurpose Accurate Easy DLASFSBEE
Automatic shutdown. Low battery reminder. Oxygen solubility is affected by temperature, atmospheric pressure and salinity. Our instrument has a temperature compensation function, which can meet normal use. Detachable probe, easy to replace, equipped with 6 probe protection covers. The film in the protective cover cannot be separated. After using for a period of time, the test value is inaccurate, the calibration is still inaccurate, and the film sleeve needs to be replaced. It is very suitable for measuring the dissolved oxygen level and temperature in various aquariums, swimming pools, ponds, freshwater aquaculture, marine aquaculture, school teaching experiments, laboratory sterile environment, aquaculture, scientific research and other fields. Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, usually expressed in milligrams/L (ppm) and saturation rate (%), that is, the percentage of dissolved oxygen in 1 liter of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0 mg/L, and most of the dissolved oxygen meters on the market range from 0.0-20 mg/L. When measuring and calibrating, there is no need to open the protective cover of the electrode, just put the electrode in the solution for measurement. The dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with an aurora sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode, but allows oxygen to pass through the membrane to react and measure the concentration.
