Features:1. Abundant detection functions: the three monitoring indicators of blood oxygen saturation (SpO2), pulse rate (PR), and blood perfusion index (PI) are fully mastered.2. One-key detection: After turning on, put your finger in the measuring position and it will automatically detect, and the measurement data can be read after about 8 seconds.3. Structure and appearance: compact structure and cartoon appearance design, adaptive to the size of children's fingers in the bag, using soft skin-friendly silicone finger pads, suitable for children from 6 months to 12 years old.4. Scope of application: measure children's pulse oximetry, pulse rate and oximetry index.5. OLED screen: Show clear results. The product is lighter, low power consumption and high brightness. The low battery indicator provides accompaniment to monitor children's SpO2.Description:The three monitoring indicators of blood oxygen saturation (SpO2), pulse rate (PR), and blood perfusion index (PI) are fully mastered.Specifications:Display content: blood oxygen saturation, pulse rate, pulse intensity bar, waveform graph, heartbeat indicator, battery powerBlood oxygen saturation: range: 70%-100%, accuracy: ±2%, not verified below 70%Pulse rate display: range: 25~250bpm, accuracy: ±2bpmPackage Included:1 * Oximeter1 * Lanyard1 * ManualNotes:1.
