LED Display Blood Oxygen Monitor Fingertip

Color LED display Blood oxygen value display range: 70-100% pulse rate value display range: 30-240bpm Resolution: SpO2 = 1%, pulse rate = 1bpm Accuracy: ± 1% for 70% ～ 100% of SpO2, no definition for less than 70%, and ± 2 BPM or ± 1% for pulse rate, whichever is greater Power requirements: 2 No.7 1.5V alkaline batteries It has strong resistance to environmental light and weak perfusion Display format: LCD display: blood oxygen saturation display: 70 - 100%; Pulse rate display: 30-240 BPM, 3-digit seven segment digital display; Pulse wave display: bar graph display; Low battery voltage indication: LCD symbol. Power requirements: 2 No.7 1.5V alkaline batteries, voltage range: 2.6 - 3.6V. Power consumption: less than 30 ma. Resolution: SpO2 was ± 1%, pulse rate was ± 1 bpm. Measurement accuracy: blood oxygen saturation in 70% - 100% segment is ± 2%, less than 70% undefined, pulse rate is ± 2 bpm. Measurement performance under weak perfusion: it can correctly display blood oxygen and pulse rate when the pulse filling degree is 0.5%. Anti interference ability of ambient light: compared with the measurement value in dark room, the deviation of blood oxygen measured under indoor natural light and existing lighting source is less than ± 1%. With function switch, it will shut down automatically after 8 seconds without finger insertion. Alarm prompt Test value: blood oxygen saturation, PI, heart rate detection
