More Accurate Oxygen Monitor Finger Adults Oximeter: AILE pulse oximeter is composed of advanced MCU chip and high performance acceleration sensor. The blood oxygen signal is detected by the photoelectric detection principle, which greatly improves the measurement accuracy. The accuracy of the oxygen monitor can reach plus or minus 2% More Accurate Heart Rate Monitor Finger Oxymetre: AILE pulse-oximeter speed reaches 99%, just put your finger on the grating to measure the light reflected/transmitted through the skin. Combined with advanced filtering detection algorithm, it can realize continuous, fast and accurate monitoring of human arterial oxygen saturation and pulse frequency. After the finger is placed in the pulse monitor, the self-induction monitoring, the data can be clearly obtained within 8 seconds Hardware Upgrade: AILE oxygen saturation monitor consists of ABS shell, acrylic panel, high-speed security chip. High quality materials and components make the oxygen sensor accurate and durable (thousands drop tested). Improved LED screen with high-brightness large red font display allows you to comfortably read blood oxygen levels and real-time heart rate at a glance in any environment Easy Operation: The finger pulse oximeter adopts one-button measurement, and the measurement results are displayed on the large digital LCD display. Reading in both directions. You can change the display orientation each time you press the oxymeter button. Power off after 8 seconds after removing your finger, saving energy. The springs are designed on the same side, allowing customers to safely remove the battery (avoiding damage and loss of accuracy due to battery swapping) Wide Audience: AILE fingertip oximeter is based on advanced MCU chip, oxymetre smart silicone sats probe, using silicone material, softer, warmer and more comfortable, ergonomic design, can be widely used in children (2+ ), teenagers, adults, seniors, pregnant women, athletes or anyone interested. You can easily measure SpO2 and pulse levels after flying, skydiving, running, hiking, biking, swimming, mountaineering, skiing, high altitude climbing, eating, waking up and more.
