PXY-133 Wireless Finger Pulse Oximeter


Model Shown: PXY-133

This Finger Pulse Oximeter continuous measures the oxygen saturation level of the blood and the recorded data can be transferred to a computer. Data can be recalled later to check trends. The measurements can be sent in realtime over wirelessly, if equipped. The BP will also be measured. This sensor can be used as a general SpO2 meter for hospital use or home use.



 - Integrated with SPO2 probe and processing display module.

 - Can be used in hospital, home, community medical treatment center, sports healthcare, etc.

 - Can measure SPO2 and PR accurately.

 - SPO2 and PR display, PR waveform and bargraph display.

 - Pulse rate sound function.

 - Battery voltage indicator.

 - 4 Direction Display.

 - Four levels adjustable brightness.

 - Alarm function; can set upper and lower limits.

 - Data storage.

 - USB interface to computer, software can analyze and print the data.

 - Low power consumption; shut off automatically when no signal.

 - Charge by AC transformer or PC USB port.

 - Integrated with SpO2 probe and processing display module.

 - Simple operation and low power consumption.

 - Operation menu for the function setting.

 - SpO2 value display.

 - The display mode can be changed.

 - Screen brightness can be changed.

 - Measured data beyond limits and low-voltage alarm function, the upper/down alarm range is adjustable.

 - Low-voltage indication: low-voltage indicator appears before working abnormally from low-voltage, and with alarm function.

 - 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.

 - Automatic power off function: when the device is actively measuring, it will automatically power off within 5 seconds if finger falls out of probe.

 - 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%.

 - Interference resistance capacity against ambient light and measurement performance at low perfusion.

 - Sell in standard:

 - Hanging rope

 - User manual

 - Data line

 - Disk (PC software)

 - Power adapter
