Technical Parameters

■ Display Mode: Dual color OlED Display,the display direction can be changed SpO2,Pulse rate,Pulse bar,waveform(4 display modes) 

■ SpO2 measuring range: 0%-100%

■ Accuracy: When the SpO2 measuring range is : 70% to 100% ,the permission of absolute error is (±) 2%; below 70% unspecified 

■ Resolution: SpO2: 1% Pulse Rate: 1bpm

■ Pulse Ratio: 30-250 BPM

■ Measurement Performance in Weak Filling Condition: SpO2 and pulse rate can be shown correctly when pulse filling ratio is 0.4%, SpO2 error is (+, -)4%, pulse rate error is ±2bpm Or 2%(select larger).

■ Resistance to surrounding light:The device between the value measured in the condition of man-made light and that of darkroom is less than (±)1%

■ Alarm function:Detected data going beyond limit alarm (when the SpO2 is below 90%,or the pulse rate is not between 50bpm and 120bpm, the alarm occurs);Low power alarm
