Principle of the CMS50E 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
Operation menu for the function setting
SpO2 value display
Pulse rate value display, bar graph display
Pulse waveform display
The display mode can be changed
Screen brightness can be changed
A pulse rate sound indication
With measured data overruns limits and low-voltage alarm
functionthe upper/down alarm range can be adjustable
Battery capacity indication
Low-voltage indication: low-voltage indicator appears before
working abnormally which is due to low-voltageand with alarm
With SpO2 value and pulse rate value of storage, the storage data
can be uploaded to computers）
Real-time data can be transmitted to computers
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.
