Small in size, light in weight, and easy to carry; simply place in a pocket or bag. Simple operation: place a finger on the monitor, and the screen will display the measured values directly. The high-definition screen shows SpO2 blood oxygen level, perfusion index (PI%), pulse rate (PR bpm), pulse strength (bar graph), pulse waveform, and battery status. The continuous bar chart indicates stronger pulse intensity with higher display levels. Results can be viewed in multiple ways with one-key operation for user convenience. Features high-precision sensors that support fast measurements and deliver accurate data, suitable for non-invasive monitoring of oxygen saturation and pulse rate in both hospital and home settings. Smart power-saving function automatically turns off the device after 5 seconds of inactivity. Built-in soft silicone pad gently secures the finger without added pressure for comfortable use.
