Use of Oxygen Monitors for Nitrogen, Argon, or Cryogenics and Where They Are installed

by PureAire Monitoring Systems, Inc  (Aug. 19, 2016)

An oxygen deficiency monitor or O2 monitor is found in many settings where colorless, odorless gases -- including nitrogen, argon, CO2, and cryogenic gases -- are used. Always monitoring, the oxygen detector can tell when gas levels rise above those deemed safe, and let off a timely alarm. Learn which settings commonly use ...

Pulp & Paper: Real-Time BOD & COD Monitoring

by Real Tech Inc.  (Aug. 17, 2016)

A pulp and paper facility in Ontario, Canada has implemented an effective solution for monitoring chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in real-time.

Oxygen Monitors for the New Millennium

by PureAire Monitoring Systems, Inc  (Mar. 8, 2013)

Oxygen monitors have become a required piece of safety equipment for many industrial and laboratory environments, where the release of certain toxics can create an area unsafe for living beings (human or animal).  When making a purchasing decision on any oxygen detection monitor, one need look no further than the sensor cell found at the ...

Boiler Dissolved Oxygen Control

by IC Controls Ltd.  (May 20, 2015)

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 ...

ppb Dissolved oxygen measurement

by IC Controls Ltd.  (Jan. 1, 2005)

Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible for costly replacement of piping and equipment by corrosive attack on metah. what is Dissolved ...

Reliable oxygen levels in trout farms with LDO

An adequate level of oxygen must be maintained in the water of fish farms. If the level is too low, fish production suffers. Stocking density, feed intake and resistance to disease are just three of the key variables that significantly affect profitability and are directly dependent on the oxygen concentration. Kirsten and Alexander Tautenhahn ...
