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 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.

B. Pulse rate value display, bar graph display 
C. Pulse waveform display 
D. Low-voltage indication: low-voltage indicator appears before working abnormally which is due 
to low-voltage   
E. Automatically power off function: when the device is under the state of measuring interface 
(without external probe), it will automatically power off within 5 seconds if the finger falls out of 
probe. 
F. The display mode can be changed 
G. Screen brightness can be changed   
H. With pulse rate sound indication   
I. With alarm function 
J. With SpO

 and pulse rate value record function, the record data can be uploaded to computer. 

K. It can be connected with an external oximeter probe( optional ) 
L. Data can be observed on computers synchronously by PC software 
M. With two kinds of data transmission mode:data line and bluetooth.
