Sale price Price $195.00 Regular price Unit price  per 


The Altus Meso is the second generation Altus smart tank monitor from Aithre with all the same innovative functionality now packaged in a miniature form factor.  Altus Meso wirelessly pairs to your iOS device and Apple Watch to display pressure, flow rate, and time remaining, including oxygen trend graphing and much more, now using only USB power.  This small device makes your portable oxygen tank more usable and accessible without the expense and hassle of a built-in system.  

Includes high-pressure quick-disconnect sensor, high pressure-rated tee fitting expansion for 1/8" NPT size ports (typical on all oxygen tanks), USB power bank, and iOS/WatchOS app downloadable from the Apple App Store.

Installation is easy.  Just empty your tank and insert the supplied sensor fitting between your tank and the old pressure gauge.   For added convenience, your Altus Meso can come preinstalled with any new Aerox tank for an exclusive low $149.99 upgrade plus the cost of a tank.  Call Aerox for details on this special offer only available with new Aerox tanks.
