WARNING: Do not use any unapproved fittings on your oxygen bottle as the fittings Aithre provides are special high-pressure fittings designed to withstand 5000 plus PSI. Aithre fittings are designed for oxygen tank use.  Hardware store fittings are only rated to 100-300 PSI, which is not sufficient.   

The Altus Meso is the second generation Altus smart monitor from Aithre with all the same innovative functionality now packaged in a miniature form factor.  Born in aviation, the Altus Meso provides critical oxygen level information to help keep pilots and passengers safe.  Now adapted for skiing, backcountry, and mountaineering, the Altus Meso wirelessly pairs to your iOS device and Apple Watch to display pressure and notifications of low oxygen.  This small device makes your portable oxygen bottle more usable and accessible so you can track exactly how much oxygen you are using and how much you have left without removing your bottle from your pack.
