Rugged Dissolved Oxygen And Dissolved Oxygen

Amperometric oxygen sensor for water wastewater and utilities.

Rugged dissolved oxygen and dissolved oxygen. This professional waterproof meter complies with ip67 standards and measures do barometric pressure bod and temperature. In aquatic environments oxygen saturation is a relative measure of the amount of oxygen. Most relevant lists of abbreviations for rdo rugged dissolved oxygen. For example in freshwater under atmospheric pressure at 20 c o 2 saturation is 9 1 mg l.

Dissolved oxygen do is measured in standard solution units such as millilitres o 2 per litre ml l millimoles o 2 per litre mmol l milligrams o 2 per litre mg l and moles o 2 per cubic meter mol m. At high cell concentrations the rate of oxygen consumption may exceed the rate of oxygen supply leading to oxygen limitations. Measure dissolved oxygen levels without the difficulties of membrane replacement by using the thermo scientific orion rdo dissolved oxygen probe. The concentration of oxygen dissolved in a liquid can be measured using the amperometric or optical measuring principles.

11 8 oxygen demand for aerobic microorganisms. From the air oxygen can slowly diffuse across the water s surface from the surrounding atmosphere or be mixed in quickly through aeration whether natural or man made 7 the aeration of water can be caused by wind creating waves rapids waterfalls ground water discharge or other. How dissolved oxygen enters water. Shijie liu in bioprocess engineering second edition 2017.

Rugged do meter for efficient and flexible field water testing. The hi98193 is a rugged portable dissolved oxygen do meter designed for demanding applications. Measuring dissolved oxygen in water and treatment to maintain proper dissolved oxygen levels are crucial functions in a variety of water treatment applications. Rdo rugged dissolved oxygen probe uses optical do technology for problem free measurement.

Dissolved oxygen do is an important substrate in aerobic fermentations and may be a limiting substrate since oxygen gas is sparingly soluble in water. The hi98193 is supplied complete with all accessories to perform a do measurement packaged into a durable carrying case. Dissolved oxygen enters water through the air or as a plant byproduct.
