The Aladin

system consists of four units:
1
The Oxy2 is fitted “in line“ to the inhalation hose of the semi
closed rebreather (SCR) and measures the actual oxygen fraction
of the inspired gas mixture. This information is transmitted to a
paired wireless Aladin
®
Air Z O
2
. This is the basis for the calcu-
lation of both oxygen toxicity and decompression, based on the
real values of the inhalation gas.
2
With open circuit breathing systems a
pressure transmitter
is used, which is installed at the high pressure outlet of the first
stage regulator. It measures tank pressure and transmits the
results to the dive computer, where they are further analysed for
the calculation of gas mixture consumption and dive data.
3
The
dive computer
displays only important data. The upper
display shows general dive data and decompression data. The
lower display shows data from either an Oxy2 or pressure trans-
mitter.
