    The saturimeter is a very small instrument. It is used by healthcare workers in the hospital (even in emergency situations) to monitor the oxygen level in a patient's blood allowing doctors to intervene if oxygen falls below safe levels. The ease of use, associated with the fact that it is a non-invasive and painless instrument, has extended its use also in the domestic environment.In addition to the measurement of oxygen in the blood, the saturimeter also allows to monitor the heart rate.

    The Jonker pulse oximeter version 1.0 arrived in just four days and at the moment it works very well. It is equipped with the guarantee, the cable to hang it around the neck and the instructions also in Italian. The instrument has some importance for checking the correct functions of the body, by measuring the percentage of hemoglobin in the blood. The display in a healthy subject should be more than 99%. As you can see in the photos mine reaches 98% on the finger of the left hand, while it touches the 99% with the fingers of the right hand (trust even without photographic proof)

    Very good product and accurate... I thought the brand name of the fingertip pulse oximeter was Boxym but it is Yonker.... nevertheless... it is almost accurate (up to ±3% depending on humidity, room temperature and atmospheric pressure)... I check my heart rate manually and electronically (via fingertip pulse oximeter Model: YK-80B) at the same time and the findings of measurement was almost the same. Manually (using fingers for 1 minute) the heart rate was 70 bpm while electronically (using the new fingertip pulse oximeter) was 67 bpm.... Value for money.... I recommend that product for sure....

    Very good accuracy and great response time. This product is as good as the Japanese medical pulse oximeter that was using when I was in the hospitalization.
