Product Description

MEECO moisture analyzers offer accurate and reliable testing for high-purity applications in Alberta, whether used at Processing Facilities, Pharmaceutical manufacturing, Semiconductor Manufacturing,Research and Scientific Labs, Shielding Gases in Welding, and other Specialty Gases. The AquaVolt+ provides precise, on-line moisture monitoring for high-purity applications, such as semiconductor manufacturing, specialty gas applications, mobile cart applications, and research and industrial labs. Moisture measurement is critical at all points of natural gas processing, such as point of extraction, the drying process, distribution lines, and point of use. For high-purity gas applications, moisture monitoring is essential to product production, purification, cylinder reclamation, and packaging, as well as final quality control. In the industrial packaged gas plant, moisture monitoring is also used during various stages of production, such as reclamation, container preparation, filling, and quality control.

Thoughtful features save space, ease operation, and boost confidence, including:

• Compact, flexible footprint:Two analyzers fit neatly into ONE 19” RACK!
• Ease of Use:User-friendly keypad interface, bright vacuum fluorescent display (VFD) and helpful menu-driven prompts make it simple to specify, to configure, and to start up for your specific application
• Flash upgradable software: Easily upgrade unit software via RS232 port
• Adjustable outputs: Flexibility to change output scales in the field. No need to replace electronic components or access the internal components. Simply access menu via Mode/Enter key and select output scale.
• Mass Flow Control: Select your sample gas from the main menu and the microprocessor automatically adjusts the mass flow controller to the proper set point.
• On-line verification:Conveniently check proper cell operation using simple Delta Flow procedure to verify sensor linearity and performance on-line.
• Consistency and precision:The reliability and accuracy of MEECO’s time-proven electrolytic sensor are unique among its peers. When you have been doing something since the early 1950’s, you approach perfection…

Principle of Operation:

Based on Faraday’s Law of Electrolysis, the AquaVolt’s sensor absorbs and electrolyzes moisture at fractional parts-per-million or parts per billion (ppm or ppb). 100% of the sample moisture is absorbed by a phosphorus pentoxide (P2O5) film that covers two spirally-wound electrodes embedded in a hollow glass tube. When the sample gas enters the cell at a known flow rate, the film absorbs all the moisture molecules present. By applying an electrical potential (voltage) to the electrodes, each absorbed water molecule is electrolyzed, generating a finite current. This current is precise and proportional to the amount of absorbed water. It is a direct measurement of the water vapor present in the sample gas.
