Product description
0.96" Dual-color OLED display Pulse Oximeter SpO2 Sensor Introduce Oxygen saturation Oxygen is carried in the blood attached to haemoglobin molecules. Oxygen saturation is a measure of how much oxygen the blood is carrying as a percentage of the maximum it could carry.One haemoglobin molecule can carry a maximum of four molecules of oxygen, if a haemoglobin molecule is carrying three molecules of oxygen then it is carrying 3/4 or 75% of the maximum amount of oxygen it could carry.The range of oxygen saturation for a healthy individual is between 92-100%. Principles 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 and near-infrared zones. Operation principle of the instrument is: photoelectric Oxyhemoglobin Inspection Technologe is adopted in accordance with Capacity Pulse Scanning and Recording Technology, so that 2 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.
Main features Operation of the product is simple and convenient The product is small in volume, light in weight (total weight is about 50g including batteries) and convenient in carrying Power consumption of the product is low and the 2 originally equipped AAA batteries can be operated continuously for 20 hours The product will automatically be powered off when no signal is in the product within 5 seconds Pulse wave display columniation display and the waveform display Blood oxygen prob and display processing module are combined together Changeable display Changeable screen luminance Display mode could be saved after power off
