Instructions
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.
Major Feature
Integrated with SpO2 probe and processing display module
Small in volumelight 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.
