A pulse oximeter uses two frequencies of light (red and infrared) to determine the percentage (%)of hemoglobin in the blood that is saturated with oxygen. The percentage is called blood oxygen saturation, or Sp 02. A pulse oximeter also measures and displays the pulse rate at the same time it measures the Sp02 level.

The finger clip oximeter is a non-invasive method for monitoring patient blood oxygen saturation, mainly used for monitoring blood oxygen saturation in clinical departments, wards, outpatient clinics, home and community healthcare, as well as outdoor sports, mountaineering, cycling, and long-distance running.

Joytech has developed several models of portable pulse oximeters right now and will keep in developing.

The real-time monitoring of athletes' blood oxygen by a blood oxygen meter helps to understand their blood circulation after heavy exercise, and guide the determination of athletes' exercise volume. Joytech fingertip pulse oximeter comes with a lanyard and storage bag which is portable for daily use.
