CONTEC CMS50NA OLED Fingertip oxymeter spo2,PR monitor Blood Oxygen Pulse oximeter

      Pulse oximeters give an estimated oxygen saturation level value. Several research studies and an FDA 2021 safety communication have found that certain physical traits, including but not limited to darker skin pigmentation and melanin, may make the oxygen level estimated value appear higher than it actually is. Users are strongly recommended to establish a baseline value when healthy and at rest. It is recommended that users consult a licensed healthcare provider or professional on how to interpret user readings based on physical traits or characteristics. The oximeter is a device for measuring blood oxygen saturation. Insisting on using oximeter and monitoring blood oxygen content can effectively prevent the occurrence of danger. In case of hypoxia, oxygen can be replenished at the first time, greatly reducing the chance of disease. 1.Introduction( no battery) The Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through finger. 2.Features1) Can measure SpO2 and Pulse Rate2) SpO2 and Pulse Rate display,Pulse Rate waveform and bar graph display 3) Battery voltage low indication4) The display mode can be changed.5) Screen brightness adjustable3.PerformanceSpO2 measurement range: 0%~100%Accuracy: 70%~100%: ±2% 0%~69%: unspecifiedPR measurement range: 30bpm~250bpmAccuracy: ±2bpm or ±2%, whichever is greater.Resolution: SpO2: 1% PR: 1bpmMeasurement 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 ±2 bpm or ±2%, whichever is greater.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%.Working current: ≤30mAPower supply: two “AAA” batteriesSafety classification: type BF applied part4.Physical characteristicDimension: 60mm(L) × 34mm(W) × 33mm(H)
