Narigmed’s oximeter is suitable for various environment measurements, such as high altitude area, outdoors, hospitals, homes, sports, and winter season, etc. FRO-200 is also applied to kinds of populations, such as children, adults, seniors. It is easy to handle the physiological disturbs, such as Parkinson, poor blood circulation. Usually, most current exist oximeters are hard to output parameters (relatively slow or invalid output) under cold environment, poor blood circulation. However, Narigmed’s oximeter can output parameters quickly within 4~8 seconds only.Compare to others, only Narigmed’s oximeter can provide such various conditions and wide populations.
