Hello,
In the search of portable CO detector and/or easy pulse oxymeter, I’ve found Aythre products:
pulse oxymeter fixed on headset (need a USB power):
USB-key format CO detector:
The pulse oxymeter is also linked to CO detector and can provide haptic feedback on some threshold alert. Unfortunately, they are managed also through an Iphone app..
Aithre is spelt with an “i” not a “y”
Hi All,
Just looking at two options of cylinders;

Y- 4.76 m3
W- 11.03 m3
Nominal Pressure at 15°C (bar) 230 bar
Cylinder being filled -

How many refills am I likely to get? Not sure where to start with the maths.
