Product Description


The MD300C23 is an FDA approved portable non-invasive blood oxygen meter used in a medical setting to measure blood oxygen saturation level or (SpO2) and pulse rate. This pulse oximeter provides spot checks for infants1, children1 and adults.

MD300C23 oximeter provides accurate readings of a person’s oxygen saturation and pulse rate along with pleth waveform. The pleth waveform (photoplethysmograph or PPG) shows the change in blood volume with each heart beat and is an indication of the heart condition and perfusion level. A strong pleth wave would ensure the reliability of the oximeter readings.

The fingertip pulse oximeter has been approved by FDA (USA), PMDA (Japan) and CMDCAS (Canada).

The digital display can show data in six directions making it easy for the patient and caretaker to read.

MD300C23 display modes

This pulse oximeter combines advanced technology with a stylish, wearable design. The large bright blue LED display allows you read in the dark and severe weather condition

The outstanding interference resistance capacity against ambient light along with wide-range accurate measurement even in low perfusion make this fingertip pulse oximeter one of the best oximeters in the world. Deviations are less than ±1% where comparing readings taken in indoor natural lighting against those taken in a dark room.
