CMS50D2 pulse oximeter

Main performance 1) Display Mode：0.96" Dual-color display(blue and yellow) 2) SpO2 Measuring Range：0%～100%, (the resolution is 1%).   Accuracy：70%～100%：±2% ,Below 70% unspecified. 3) PR Measuring Range：30 bpm～250 bpm, (the resolution is 1 bpm)   Accuracy：±2 bpm or ±2% (select larger) 4) PI Measuring Range: 0 %~ 20％   Accuracy：When the PI measure range is 1%~20%,the permission of absolute error is ±1%             When the PI measure range is 0%~0.9%,the permission of absolute error is ±0.2% 5) 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 ±2 bpm or ±2% (select larger). 6) Resistance to surrounding light: The deviation between the value measured in the condition of man-made light or indoor natural light and that of darkroom is less than ±1% 7) Power Consumption：less than 80 mA 8) Voltage: DC 2.6 V - 3.6 V 9) Power Supply:1.5 V (AAA size) alkaline batteries × 2   10) Safety Type:Interior Battery，BF Type Accessories 1)One hanging rope（optional）； 2)One User Manual. Physical characteristic Dimensions：60(L) mm × 30.5(W) mm × 32.5 (H) mm Weight：About 50g (with the batteries)

Major Features 1)SpO2 value display 2)Pulse rate value display, bar graph display 3)Pulse waveform display 4)PI value display 5)The display mode can be changed 6)Low-voltage indication: low-voltage indicator appears before working abnormally which is due to low-voltage 7)Pulse sound indication and over limit indication
