Mountain High Oxygen has released its next generation of Electronic Delivery System (EDS) Pulse Demand oxygen controllers, the O2D1-2G and O2D2-2G.
The new Pulse Demand systems incorporate all of the benefits of the company’s legacy controllers but with many improvements, according to company officials.
“We started with the control switch: The EDS unit now incorporates a MIL spec ruggedized easy-to-grip rotary control switch providing improved reliability, increased ease of function and visibility,” officials said. “This switch also has very positive position detents for excellent tactile feedback, making it resistant to changes from causal rubbing or bumping.”
Also improved was the manifold design to allow for better breathing response and effort tracking, officials noted.
“This, combined with a new circuit board, as well as a new micro-controller, gives improved power-conserving operations with even less RFI emissions, better respire-metric tracking and dispensing of oxygen in finer resolution resulting in smoother steps from altitude and breathing changes,” officials added.
Other improvements include a dedicated bi-color system battery status light allowing easier monitoring and definitive indication of battery condition. Also, audio alerts and warnings are louder.

Unfortunately they will be god awful expensive.
