Altus Meso Portable Oxygen Tank Pressure Monitor - With iOS App - Black

WARNING: Do not use any unapproved fittings on your oxygen tank as the fittings Aithre provides are special high-pressure fittings designed to withstand 3000 plus PSI. Hardware store fittings are often only rated to 100-300 PSI, which is not sufficient for oxygen tanks. Risk of injury or death if you use non-Aithre fittings.   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 and a decay-based flow rate, including oxygen trend graphing and much more, now using only USB power. This small device makes your portable oxygen bottle more usable and accessible.   Includes high-pressure quick-disconnect sensor, high pressure-rated T-fitting expansion for 1/8" NPT size ports (typical on all oxygen tanks), USB power bank, and iOS/WatchOS app.   Installation is straightforward. First empty your tank, then
