The Use of Rapidox Oxygen Analysers in Industrial Nitrogen Gas Applications

Nitrogen gas is the most commonly used of industrial gases. It is used within a wide range of industries, including chemicals, pharmaceuticals, steelmaking and other metals refining. A selection of metal based nitrogen applications include annealing, sintering, brazing and hardening and tempering. By using nitrogen based process systems, product quality and consistency is greatly improved and the metal protected from oxidation. Benefits also include increased production in the form of faster start-ups and fewer process interruptions.

Cambridge Sensotec’s Rapidox zirconia oxygen gas analysers are designed to measure ppm levels of oxygen which make them ideal for nitrogen gas based applications. Measurement of residual oxygen levels is critical in order to maintain a consistent nitrogen atmosphere. The presence of oxygen can increase the chances of oxidisation resulting in a compromise in quality in parts produced. By using the Rapidox gas analyser in the process, users can save on costly part rejects or failures.

The Rapidox range of gas analysers offer fast, accurate and reliable oxygen measurements ensuring quality and efficiency. Each Rapidox analyser is supplied with powerful software allowing users to data log oxygen measurements to aid quality control and traceability. The software also allows for the control of external devices, for example a proportional flow control valve to optimise the use of nitrogen, which leads to significant cost savings by reducing nitrogen usage.
