3. Principle and Precautions
3.1 Measuring Principle
The principle behind the Oximeter is as follows: An empirical data processing formula was drawn up according
to the Lambert Beer Law as per the Spectrum Absorption Characteristics of Reductive Hemoglobin (Hb)
and Oxyhemoglobin (HbO
Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scanning & Recording
Technology, so that two beams of different light wavelengths can be focused onto a human nail tip through a
perspective finger-type clamp sensor. The measured signal is obtained by a photosensitive element and the
information thus acquired is shown on a screen after processing by electronic circuits and a microprocessor.
