WARNING: VERY HIGH FLOWS MAY PRESSURISE THE SENSOR AND

The Analox O2 EII Pro comes complete with a unique sampling dome which allows you
to directly apply the analyser to the outlet on your nitrox tank.
1.
Ensure the sensor saver is removed. Push the sampling dome into the sensor
aperture.
2.
Ensure the Analox O2 EII Pro has been calibrated as per the instructions in Section
3.2.

Very slowly open the pillar valve with your right hand until gas can just be heard
quietly hissing out.

Once the pillar valve has been opened and the nitrox is heard gently hissing, hold
the O2 EII Pro in your left hand and press the sampling dome firmly against the
tank outlet.
CAUTION: OPEN TANK VALVE EXTREMELY CAREFULLY BEFORE THE O2 EII PRO
IS APPLIED
5.
Close the pillar valve after fifteen seconds when a stable reading is observed on the
O2 EII Pro.
