Fingertip Pulse Oximeter 20A

Features:
Integrated with SpO2 probe and processing display module
Small in volume, light in weight and convenient in carrying
Operation of the product is simple, low power consumption
Display parameters: SpO2 value, Pulse rate value, bar graph, Pulse waveform, pulse mark, battery volume,;
Pulse synchronization function. The pulse waveform, pulse mark, and bar graph are synchronous with the pulse beep.
Different display mode. There are four display modes, and the display mode can be changed by pressing the key;
Screen brightness can be changed
Pulse Beep function. The pulse beep is synchronous with the pulse and can be on/off by press key;
Alarm function. When the measurement result is out of the pre-setting threshold, the beep will alarm and the measurement result will sparkle;
Real time voltage indication: Voltage indicator always appears and inform the users to replace the new battery;
Automatically power off function: When the device is under the state of measuring interface. It will automatically power off within 8 seconds if the finger falls out of probe.
Display format can be saved after power off.
