<p>The new product wellue sleep O2 monitor can track your O2 level and pulse rate and other body values.</p> <p> </p> <p>It can be used for daily and sleep monitoring. </p> <p> </p> <p> </p> <p> </p> <p>Model：visualoxy</p> <p> </p> <p>Battery type: Rechargeable lithium-polymer battery</p> <p> </p> <p>Charge time: 2~3 hours</p> <p> </p> <p>Measurement accuracy verification: The O2 level accuracy has been verified in human experiments by </p> <p>comparing with arterial blood sample reference measured with a COoxi-meter. The pulse rate accuracy has been verified by Emulator. Pulse O2 meter measurement are statistically distributed and about two-thirds of the measurements are expected to come within the specified accuracy range compared to CO-oxi-meter measurements.</p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p> <p>O2level range: 70% to 100%</p> <p> </p> <p> </p> <p> </p> <p>O2level Accuracy (Arms) 80-100%: ±2%, 70-79%:±3%</p> <p> </p> <p> </p> <p> </p> <p>PR range: 30 to 250 bpm</p> <p> </p> <p> </p> <p> </p> <p>PR accuracy ±2 bpm or ±2%, whichever is greater</p> <p> </p> <p> </p> <p> </p> <p>Wave length: 660-940nm</p> <p> </p> <p> </p> <p> </p> <p>Range: 0 to 99999 steps</p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p> <p>Sleep analysis</p> <p> </p> <p> </p> <p> </p> <p>Record: parameters O2, pulse rate, motion</p> <p> </p> <p> </p> <p> </p> <p>Record interval: 4s</p> <p> </p> <p> </p> <p> </p> <p>Drop analysis: Yes</p> <p> </p> <p> </p> <p> </p> <p>Mobile APP: iOS iOS 9.0 or above, iPhone 4s/iPad 3 or above</p> <p> </p> <p> </p> <p> </p> <p>Android Android 5.0 or above, with Bluetooth 4.0 BLE</p> <p> </p> <p> </p> <p> </p> <p>Support PC software: Yes</p> <p> </p> <p></p> <p> </p> <p>This product is intended for sports or aviation use only. It should not used to diagnose or treat any medic
