algorithms* and sensors provide extremely accurate one touch calibration.
Note: Failure to account for environmental factors can produce up to 6.7%
error.
 Oxygen is compensated for temperature, barometric pressure and RH.
 Helium is zeroed when the oxygen is calibrated with air or 100% oxygen.
Algorithms* compensate the Helium value for differences in the thermal con-
ductivity of Oxygen and Nitrogen enabling the AII-4001 to precisely measure
any combination of Helium, Oxygen and Nitrog en.
The large backlit LCD is easily read even in low light condition and provides
additional informatio n to the user:
 Temperature, barometric pressure and RH values of the sample gas.
 For added safety, the Maximum Operating Depth (MOD) PO2 @ 1.4 ATA of
