CMS50EA Fingertip Pulse Oximeter Spo2 Monitor OLED

// Introduction The Pulse Oximeter can be used in measuring oxygen saturation and pulse rate through finger. Features 1)Integrated SpO2 sensor and display module2)Small in volume, light in weight and convenient in carrying3)Easy to operate, low power consumption4)Operation menu for function settings5)SpO2 value display6)Pulse rate value display, bar graph display7)Pulse waveform display8)Display direction can be changed9)Screen brightness can be changed10)Pulse rate sound indication11)With measured data overruns limits and low-voltage alarm function, the upper/lower alarm limit can be adjusted12)Battery capacity indication13)Low-voltage indication: Low-voltage indication appears before working abnormal caused by low voltage.14)Data storage function, stored data can be uploaded to computer Performance 1)Display mode: 1.3" 65K color OLED screen2)Screen resolution: 128*963)SpO2 measuring range: 0%~100% (resolution is 1%)Accuracy: 70%~100%: ±2%, Below 70% unspecified.4)PR measuring range: 30bpm~250bpm (resolution is 1bpm)Accuracy: ±2bpm or ±2% (whichever is greater)5)Measurement performance in weak filling condition:SpO2 and pulse rate can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is ±4%, pulse rate error is ±2bpm or ±2% (whichever is greater).6)Resistance to surrounding light: The deviation between the value measured in the condition of man-made light or indoor natural light and that of darkroom is less than ±1%.7)Power consumption: no more than 100mA8)Voltage: DC 3.6V~4.2V9)Power supply: 3.7V rechargeable lithium battery × 110)Battery working hour: 20 hours in theoretical11)Battery service life: no less than 500 times of charge and discharge12)Safety type: Internally powered equipment, Type BF applied part Accessories Standard:Lanyard 1pcUser Manual 1pcData line 1pcPower adapter 1pc Physical characteristic Dimension: 57(L) × 32(W) × 30(H) mmWeight: about 45g (with one lithium battery)
