The Oxix® Dissolved Oxygen Meter is a unique in-line analysis system of its kind. In fact, it contains in a single instrument a Dissolved Oxygen meter, a Data logger and a fieldbus control and transmission system. Oxix® is an ideal device for the measurement of dissolved oxygen in water treatment processes and plants. The Oxix® sensor does not need any calibration (it does not have membranes or capsules to replace or chemical products that can run out).
