Hemoglobin (
Hb
) and Oxyhemoglobin (
Hb
O
2
)
in
glow & near-infrared zones. Operation principle of
the device is: Photoelectric O xyhemoglobin I nspection
T
echnology 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 per spective 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.
