[MD100 DIGITAL SPO2 ]

Meditech SpO2 Module MD200 is a Low-power oxygen monitor module; the SPO2 Module is used in the sampling inspection or

measurement of the patient's oxygen saturation and pulse rate. As to the average oxygen

saturation, low-power module can send instantaneous blood oxygen saturation.

It is very useful, especially in the sleep research. The SPO2 module is compatible with the entire
