Application Note: Measure Oxygen Where it Really Matters

Performance of gaseous oxygen measurement is now redefined with METTLER TOLEDO’s amperometric systems. They not only allow reliable and stable measurement, they are inexpensive to maintain and, what’s more, do not require any gas sampling system.
 
Unwanted oxygen
Oxygen levels in industrial processes are heavily controlled to contain the risk of explosion of flammable liquids and dusts, as well as to protect products against oxidation. Not only is oxygen monitoring a critical issue in transport systems, storage tanks or centrifuges, it can also negatively affect the yield of a chemical reaction in a vessel.
 
Many solutions – which is best?
When selecting a vendor for a measurement system, technologies and solutions abound, but in many cases a trade-off exists between sufficient performance and reliability, and reasonable maintenance effort and system availability. In order to function correctly, paramagnetic systems need to protect the measurement cell from heat, moisture and / or corrosive gases. However, the more instruments there are between the process and the sensor, the longer the response time will be and the higher the probability of system failure.
