Dissolved oxygen meter is a instrument for measuring dissolved oxygen and temperature.

The dissolved oxygen probe is a thin film with a polarographic 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 the concentration can be measured.

The instrument adopts a dot LCD display, which can display the dissolved oxygen value and temperature.

Digital dissolved meter can be divided into two parts: sensor and electronic unit.

Coated oxygen electrodes are used in polarographic film sensors.

Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water.

The oxygen concentration of our dissolved oxygen meter is 0.0-20.0mg/L.

Oxygen solubility will be affected by temperature, atmospheric pressure, and salinity.

Our instrument with temperature compensation can meet normal use.
