3 Thisanalyzer offers a truly remarkable combination ofperformance features: exceptional accuracy, multi-gascompatibility, fast response speed, and widemeasurement 3050-AM is ideal for process moisturemeasurement applications including process dryers,instrument air dryers, air separators, industrial gasproduction, and quality assurance. Equipped with anon-line verification system, this state-of-the-art analyzeris designed to rapidly build and maintain operatorconfidence in its analyses. The verification systemallows you to challenge the Analyzer s sensor at willusing a zero gas to check its baseline stability toconfirm the sensor s stability and sensitivity to sub-ppmv Moisture PERFORMANCEM ulti-gas compatibilityMulti-gas compatibilityMulti-gas compatibilityMulti-gas compatibilityMulti-gas compatibilityThe Model 3050-AM combines the excellent multi-gascompatibility of the Model 2850 with a new, easy-to-useoperator interface.

4 It is completely compatible withvirtually all non-corrosive gases including inerts (He, Ar,Ne, Xe, Kr), H2, O2, N2, NO, CO2, air, and many specialtygases such as sulfur hexafluoride. A single, simplemenu selection is all that is needed to re-configure the3050-AM for a new gas type. There are no othernecessary adjustments on the , if you want to analyze industrial, high purity, orsemiconductor grade gases and need an instrument thatis compatible with a wide range of gases, turn to theModel accuracyExceptional accuracyExceptional accuracyExceptional accuracyExceptional accuracyThe Model 3050-AM is perfect for Moisture applicationsthat require accurate results. The accuracy of thisanalyzer, +10% of reading, is exceptional when youconsider that a new aluminum oxide sensor is typicallyspecified with an accuracy of +72%/-57% of reading(converted from the dew point specifications) for amoisture concentration of ppmv at psia.

The zero verificationsystem strips the Moisture from the sample gas prior toanalysis by the sensor. This allows you to verify the zeropoint of the sensor s calibration, enhancing accuracyand user confidence when monitoring in the critical 0 to10 ppmv range.

6 This system is entirely internal to theanalyzer eliminating the need to break processconnections along with the "wet-up" that would occurfrom ambient Moisture . An alarm contact alerts theoperator if the Analyzer fails verification. The verificationsequences can be started on a programmable scheduleor on manual response speedFast response speedFast response speedFast response speedFast response speedThe Model 3050-AM responds quickly to both increasesand decreases in Moisture concentration because theanalyzer employs a unique non-equilibriummeasurement technique. This technique continuouslyexposes the sensor to wet sample gas followed by drysample gas to make its analysis. With this technique,the Analyzer never needs to wait for the sensor to reachequilibrium to establish its accurate , this technique is based upon the defined,repeatable physical properties of Moisture transport to/from the sensor s surface.

7 This means that quartz-crystal technology never employs the questionableprediction software often used to "speed-up" other,more limited s unique technique makes possibleaccurate Moisture readings far faster than would bepossible under equilibrium, or continuous "wet" samplegas, operating QUARTZ-CRYSTAL SENSORTHE QUARTZ-CRYSTAL SENSORTHE QUARTZ-CRYSTAL SENSORTHE QUARTZ-CRYSTAL SENSORTHE QUARTZ-CRYSTAL SENSORThe heart of the 3050-AM Analyzer is a quartz-crystal microbalance (QCM) sensorand analysis technique developed by AMETEK specifically for highly accuratemoisture measurements. The sensor consists of a pair of electrodes that support theQCM sensor. When voltage is applied to the sensor, a very stable oscillation faces of the oscillator are covered with a hygroscopic polymer. As theamount of Moisture sorbed onto the polymer varies, the mass of the QCM changesproducing a corresponding change in the frequency of oscillation.

While this is the recommended usablerange, the Analyzer will provide measurements up to1000 ppmv so that you can capture the nature of aprocess APPLICATIONSI ndustrial gas production and quality assuranceIndustrial gas production and quality assuranceIndustrial gas production and quality assuranceIndustrial gas production and quality assuranceIndustrial gas production and quality assuranceCompressed industrial gas suppliers need accuracy tocertify compressed gas quality. They need fast dry-down response to ensure that the Analyzer comes backon-line quickly after a slug of Moisture , and they needcomplete multi-gas compatibility.

9 Compare theperformance of your present Moisture Analyzer with theModel 3050-AM : exceptional accuracy, less than 5minute dry-down time in the 100 to 1 ppmv range, andcompatibility with virtually all compressed gases,including carbon dioxide and oxygen.
