F. Measurement at low perfusion: The values of SpO2 and pulse rate can be displayed properly when pulse saturation is at 0.5%
G. Resistance to surrounding light: The difference between the value measured in the condition of indoor natural light and that of darkroom is less than ±1%
H. Resistance to interference of man-made light: Values of SpO2 and pulse rate can be accurately measured by pulse oxygen simulator
I. Automatic shutdown function: The device will power off automatically in 4 seconds when there is no finger in the device Dimension: 58(L) x 32(W) x 34(H)mm Weight: 50g (including 1.5V (AAA size) alkaline batteries x 2)
