Technical Specifications; Main Performance - PULOX PO-650B Mode D'emploi

b. Relative Humidity :≤75%
c. Atmospheric pressure:700hPa~1060hPa
3. Principle
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 (HbO2) in glow & near-infrared zones. Operation
principle of the device 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.
