Technical Parameter
It is designed for the home care and hospital customer.
Features:
1, Display Mode:0.96" Dual-color OLED display(blue and yellow)
2,Display content: SpO2 value , Pulse rate value , Pulse rate waveform ,bar graph, battery voltage display;
3,Different display mode. There are four display modes, and the display mode can be changed by pressing the key;
4,Pulse synchronization function. The pulse waveform, pulse mark, and bar graph are synchronous with the pulse beep.
5,Pulse Beep function. The pulse beep is synchronous with the pulse and can be off automatically ;
6,Alarm function. When the measurement result is out of the pre-setting threshold, the measurement result will sparkle;
