New Blood Oxygen Monitor Finger Pulse Oximeter Oxygen Saturation Monitor Fast Shipping within 24hours (without Battery)

Color LED display is a painless and noninvasive device, which shows you:Blood oxygen saturation or SpO2 level: it shows the percentage of hemoglobin carrying oxygen in the blood. The normal level is 95% or higher and the power consumption is low. It can work continuously for 24 hours.Display range of blood oxygen value: 70-100% pulse rate value - display range: 30-240 BPMResolution: blood oxygen saturation 1%, pulse 1bpmAccuracy: the 70% - 100% segment of blood oxygen saturation is ± 1%, less than 70%, undefined, and the pulse rate is ± 2bpm or ± 1%, whichever is higherAnti environment light intensity, weak perfusionDisplay format: liquid crystal display: blood oxygen saturation display: 70-100%, four directions, eight modes (upper, lower, left and right fonts respectively)Three step operation is simple and fastRemove the back cover and install the two AAA batteries.Point your finger at the red light, insert it and wait for the oximeter to turn on.Read the results in 8 to 10 seconds.Immediate and accurate results (seconds)Specifications:Project: pulse oximeterHemoglobin saturation display: 35-100%Pulse rate display: 25-250 BPMResolving power:Hemoglobin saturation: 1%Pulse: 1 BPMPerfusion index: 0.1%Measurement accuracy:Hemoglobin saturation: 2% (80% - 100%); 3% (70% - 80%); unspecified (≤ 70%)Pulse: 2 BPMPerfusion index: 1% (0-20%); unspecified (20% - 30%)Operating temperature: 5 ° C to 40 ° CStorage temperature: - 20 ° C to 55 ° CRelative humidity: 15% to 85% non condensingTest result: 5SAutomatic shutdown: 8sBattery: 2 * AAA (not included)Package size: 6 * 3.2 * 3.5cmPackage weight: approx.50g
