Principle of the CMS50DL1 Pulse Oximeter is as follows: Photoelectric Oxyhemoglobin Inspection
Technology is adopted in accordance with Capacity Pulse Scanning & Recording Technology,the
Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through
finger.The product is suitable for being used in family, hospital, oxygen bar, community healthcare,
physical care in sports (It can be used before or after doing sports, and it is not recommended to
use the device during the process of having sport) and etc.
◆ 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
◆ SpO2 value display
◆ Pulse rate value display, bar graph display
◆ Low-voltage indication: low-voltage indicator appears before working abnormally
which is due to low-voltage
◆ Automatically power off function: when the device is under the state of measuring interface.it will automatically power off within 5 seconds if the finger falls out of probe.
◆Display Mode：LED display
◆SpO2 Measuring Range：0%～100%, (the resolution is 1%).
◆Accuracy：70%～100%：±2% ,Below 70% unspecified.
◆PR Measuring Range：30bpm～250bpm, (the resolution is 1bpm)
◆Accuracy：±2bpm or ±2% (select larger)
◆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).
◆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%.
◆Power Consumption：less than 25mA
◆Voltage: DC 2.6V～3.6V
◆Power Supply:1.5V (AAA size) alkaline batteries × 2
◆Battery working hour: Theoretical number is 20hours.
◆Safety Type:Interior Battery，BF Type
