PPLICATIONS

The instrument is designed for the measurement of oxygen concentrations in a variety of medical
gas mixtures. It is recommended that the instrument

be used only as a secondary measuring

device

to verify the concentration of oxygen in gas mixtures prepared using a gas blender or

similar apparatus. The use of this monitor as a primary or only means of preparing gas mixtures is
not advised.

The monitor is capable of verifying oxygen concentrations in gas mixtures used in:

•

Anesthesia

•

Neonatal Intensive care

•

Adult Intensive care

•

Respiratory / Oxygen Therapy
