We bring for you the best quality Fingertip Pulse Oximeter CMS-50D. Technical Parameters of CMS-50D are as follow.
Features

• Display Format : LCD
• Back light : LED
• SPO2 : 35—99%
• Pulse Ratio : 30-250 BPM
• Pulse Wave : LCD Graphic Display
• Battery Voltage Low Indication : LCD signals.
• Power Requirements : Two AAA size 1.5V Alkali Battery;
• Power Consumption : less then 20 mA
• Resolution :  ±1% for SPO2 and ±1 BPM for Pulse Ratio
• Measurement Accuracy :  ±2% in stage of 70%-99% SPO2 and meaningless when stage being smaller than 70%. ±2BPM for Pulse Ratio
• Measurement Performance in Week Filling Condition : Oxyhemoglobin and pulse vaIue can be shown correctly when pulse-filling ratio is 0.4%
• Interferences Resistance Capacity against Ambient Light : Deviation is smaller than ±1% between
  l8alue of Oxyhemoglobin measured in natural lighting indoor condition and present lighting sources and that measured in dark room. It is equipped with a function switch, through which the Oximeter can be automatically powered off when no finger is in the Oximeter more than 8 seconds.
