 Measurement principle: the principle of the oximeter is as follows:

 An experience formula of data process is established by exerting Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive hemoglobin (R Hb) and oxyhemoglobin (O2 Hb) in glow and near-infrared zones; Operation principle of the instrument is to combine Photoelectric Oxyhemoglobin /inspection Technology with Capacity Pulse Scanning and Recording Technology, so that two lights with different wavelength (660nm glow and 940nm near infrared light) can be focused onto human nail through perspective clamp finger-type sensor.

Then measured signal can be obtained by a photosensitive element, information acquired through which will be shown on two groups of LEDs through process in electronic circuits and microprocessor
 Two color OLED display, more display modes 

 Low-power consumption, continuously four directions adjustable
 Low voltage indicator
 Automatically power off in 8 seconds when there is no signal
