XZR400 trace oxygen analyzer - SRP Control Systems

Oxygen AnalyzersXZR-400 SeriesOxygen AnalyzerThe XZR-400 oxygen analyzer detects trace oxygen in gas and isused to control the purity of gases such as Nitrogen, Argon, Heliumand Carbon Dioxide. It is available in wall-mountable, rackmountableand portable versions, each suited to a range ofapplications.Benefits• Reliable and repeatablemeasurements• Increased safety and cost savingsdue to a highly responsive sensor• Simple to maintain and easy tocalibrate• Quick and easy to install• Low cost of ownership due to longMSRS sensor lifetimeApplications• Control of pure gas forsemiconductor and nuclear industries• Control of gas purity for industrialgas manufacturers• Tracing leaks in glove boxes• Measuring oxygen traces in CarbonDioxide for breweries• Heat-treating applications such asgalvanizing furnaces• Simulation in laboratoriesXZR-400www.michell.com

Oxygen AnalyzersXZR-400Michell XZR-400 Clean GasAnalyzersThe XZR-400 series from Michell Instruments isdesigned to detect trace oxygen in clean gases, such as Nitrogen,Argon, Helium and Carbon Dioxide, to monitor theirpurity both in production and when used inprocesses.Michell Instruments has more than 30 years’ experience inthe measurement of contaminants in pure gases. Our customersbenefit from our comprehensiveapplication knowledge as well as the superiorperformance of our miniature metallic sealed reference sensor(MSRS) technology.The XZR-400 detects trace amounts of oxygen very rapidly.It is an ideal instrument for detecting leaks and reactingquickly to avoid costly contamination of the pure product.The rack- or wall- mount versions are best suitable for fixedinstallations, while the portable version allows spot-checkson packaged gas.Benefits• Reliable and repeatable measurementsThe miniature MSRS-based XZR-400 oxygen analyzer isresistant to pollution (such as trace hydrocarbons) and isvirtually drift-free. This means that calibration can be performedas little as only once or twice a year. Compared tothe conventional electrochemical-based oxygen analyzers,the XZR-400 saves the user not only the additional effortof calibration, but also significant cost.• Easy to calibrateThe MSRS has a sealed internal reference, enabling dryair to be used as a calibration gas for mostapplications. Calibration kits for one or two gases are alsoavailable.• Increased safety and cost savings due to ahighly responsive sensorThe XZR-400 responds to minimal changes in gas veryquickly enabling the user to react to events almost immediately.This reduces the downtime of the plant anddramatically improves the yield of the gas manufacture.• Easy to installThe XZR-400 comes in a choice of rackmountable,wall-mountable and portable models makingit appropriate for many applications, whether permanentor temporary installation is required.• Low cost of ownership due to long MSRSsensor lifetimeThe unique design of the miniature MSRSoutperforms not only all electrochemical cells but also anyconventional zirconium oxide sensors in their lifetime.TechnologyThe MSRS (Metallic Sealed Reference Sensor)technology was developed from a sensor originally designedfor ultra harsh applications in volcanoes. The miniaturedesign with the fast speed of response and long life-timemakes it the instrument of choice for oxygen measurementin a range of applications such as industrial gas purity.The MSRS responds quickly, within seconds for 90% of astep change. It is based on a metallic sealed reference whichnot only shows superior performance to other sensors on themarket, but also makes the MSRSresistant to pollution and virtually drift-free, reducing theneed for calibration.In field tests, the drift is less than 140 ppb in one month forconcentrations of oxygen at 1ppm, compared to other sensorswhich required weekly calibration.XZR-400 rangeXZR-400-WMXZR-400-PTAvailable in a wall-mountable casefor permanent fixing in a variety ofsituations.This model can also be fitted in asturdy travel-case making it idealfor applications requiring temporaryinstallation.XZR-400-RMThe rack-mountable version hasall the features of the WM and PTmodels, but fits into all standardrack sizes.www.michell.com
