Features:Display parameters: Blood oxygen SPO2 value, pulse PR value, blood oxygen bar graph, respiratory rate monitoring parameters.The product adopts LED screen display, which can display readings in two directions. Display screen: The product adopts LED screen display, which can display readings in two directions.Voltage warning: When the battery voltage is too low, which may affect normal use, there will be a low voltage warning prompt.Automatic shutdown: When no signal is generated, the product will automatically shut down after 8 seconds.Advantages: Integrating the blood oxygen probe and the processing display module, the product is simple to use, low power consumption, small in size, light in weight, and convenient to carry.Oximetry saturation: reflecting body oxygenation important indicator, the degree of oxygen saturation is generally considered to be not less than 94% of normal value, it is considered to lack of oxygen at 94% or less.Heart rate: refers to the number of times the heart beats per minute, that is, how fast the heart beats within a certain period of time.Description:This oximeter is very suitable for testing SpO2, PI and pulse rate in sports activities, such as climbing, running, cycling, etc.Specifications:Material: ABSDisplay: LEDBlood oxygen saturation:Measuring range: 70%~99%Measurement accuracy: ±2% within the range of 70%~99%, ≤70% is not definedResolution: blood oxygen saturation ±1%Heart rate pulse:Measuring range: 30BPM~240BPMMeasurement accuracy: ±1BPM or ±1% of the measured value (whichever is greater)Automatic shutdown: when no finger is inserted, it will automatically shut down in 8 secondsOperating temperature: 5℃~40℃Storage humidity: 15%~80% when working, 10%~80% storageBattery model: 2*1.5V (2 AAA alkaline, the product does not contain batteries)Material: ABS+PCPackage Included:1 * OximeterNotes:Please allow 0-1 inch error due to manual measurement.
