30mA finger oxygen level reader


30bpm pulse oxygen finger monitor


250bpm finger pulse machine

Fingertip Pulse Oximeter Ce FDA ISO RoHS Certified - easy to use ,small in volume,low power consumption


Major Applications and Scope of Application

The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the O2 concentration in the blood. It is an important bio-parameter for the respiration .For the purpose of measuring the SpO2 more easily and accurately, our company developed the Pulse Oximeter. At the same time, the device can measure the pulse rate simultaneously.
The Pulse Oximeter features in small volume, low power consumption, convenient operation and being portable. It is only necessary for patient yp put one of his fingers into a fingertip photoelectric sensor for diagnosis, and a display screen will directly show measured value of Hemoglobin Saturation.


The Pulse Oximeter can be used to measure human Hemoglobin Saturation and pulse rate through finger, and indicate the pulse intensity by the bar-display. The product is suitable for use in family, hospital (Ordinary sickroom), Oxygen Bar, social medical organizations and also the measure of saturation oxygen and pulse rate.



High precision one-key measurement, just press the key to start the measurement.

Four directions display the reading is more comfortable

Automatically detect shutdown save energy

Soft finger pad One-touch finger moulding, good fit, soft and comfortable

Small and portable the size of a matchbox, easy to carry, anytime, anywhere, just test


➢Operation of the product is simple and convenient.
➢The product is small in volume, light in weight (total weight is about 29g) and convenient in carrying.
➢Power consumption of the product is low and the two originally equipped AAA batteries can be operated continuously for 20 hours.
➢The product will automatically be powered off when no signal is in the product within 5 seconds.

Trouble Possible Reason Solution

The SpO2 and Pulse Rate can not be displayed normally


1. The finger is not properly positioned.

2. The patient's SpO2 is too low to be detected.


1. Place the finger properly and try again.

2. Try again; Go to a hospital for a diagnosis if you are sure the device works all right.

The SpO2 and Pulse

Rate are not

displayed stably


1. The finger is not placed inside deep enough.

2. The finger is shaking or the patient is moving.

1. Place the finger properly and try again.

2. Let the patient keep calm


The device can not

be turned on
