DO-5509 dissolved oxygen meter is used to measure the oxygen concentration in water. Dissolved Oxygen (DO) DO-5509 dissolved oxygen meter uses an electrode probe with temperature compensation as a sensor. The oxygen meter can self-calibrate according to the oxygen concentration value of normal atmospheric air. The sensor head of the dissolved oxygen meter will attenuate after being used for a while. If the oxygen concentration value of the standard atmosphere cannot be corrected, you can add electrolyte and replace the sensor head to repair DO -5509 Dissolved Oxygen Meter has a zero reset function, the user can adjust it to zero after using it for a period of time, and after zeroing, an atmospheric calibration must be done by the above method
DO-5509 dissolved oxygen meter: suitable for measuring oxygen concentration on general flat ground, fresh water, and air.
