The Pulse Oximeter can be used to measure human Hemoglobin Saturation and pulse rate through
finger, and indicate the pulse intensity by the bar-display. The product is suitable for use in family,
hospital
（
Ordinary sickroom
）
, Oxygen Bar, social medical organizations and also the measure of
saturation oxygen and pulse rate.

Principle of the Oximeter is as follows: An experience formula of data process is established taking
use of Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive
Hemoglobin (Hb) and Oxyhemoglobin (HbO
2
) in glow & near-infrared zones. Operation principle of
the instrument is: Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance
with Capacity Pulse Scanning & Recording Technology, so that two beams of different wavelength
of lights can be focused onto human nail tip through perspective clamp finger-type sensor. Then
measured signal can be obtained by a photosensitive element, information acquired through which
will be shown on screen through treatment in electronic circuits and microprocessor.
