PureAire Makes Oxygen Monitor for Nitrogen Generators

Nitrogen generators are most commonly used in areas where on-demand nitrogen is preferred rather than, storing liquid nitrogen (LN2) in cylinders. Nitrogen generators have a lower cost of operation, and can be used where smaller amounts of nitrogen are needed. Nitrogen generators are used in the pharmaceutical industry, testing laboratories, cryogenic facilities, welding manufactures, and ...

Dissolved oxygen’s effect on ecosystems

Dissolved oxygen (DO) is a measure of the amount of oxygen dissolved in water. It can be caused by a process of aeration of water flowing through rapids or falls, a byproduct of photosynthesis and the atmosphere. Monitoring DO levels in water may be more important than you think. From dead fish washing up on the shores of Singapore, to historically low levels of brown shrimp, DO is having an ...

Boiler Dissolved Oxygen Control

DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

Continuous on-line monitoring of dissolved oxygen in the activated sludge of a sewage treatment plant

Dissolved oxygen is traditionally measured using a Clark cell, which relies upon a gas-permeable membrane for its opera-tion. Such sensors are subject to fouling with subsequent loss of accuracy, making frequent maintenance and calibration necessary. The objective of this development was to take advantage of specific properties of microelectrode arrays, such as low flow-dependence, insensitivity ...
