Pulse Oximeter Calibration

One of the most common searches we observe is "pulse oximeter calibration".  This common search term has increased significantly over the past couple of years.  The quick answer to the popular question is no.

Smiths BCI created an information peace on pulse oximeter calibration. The oximeter calibration article can be found here.

"Pulse oximeters do not require a zero calibration because the design incorporates continuous automatic zero calibration. Gain calibration is not required because the measurement technique does not require gain accuracy."- Smiths BCI

Any type of product that has many manufacturers and has a significant range in price tend to have a range in quality.  If an oximeter is reading incorrectly it is either broken or of poor quality.

A quality oximeter such as the Nonin Onyx Vantage 9590 has been clinically tested for accuracy and durability.  Nonin also has military certification for their products.  Nonin is the only company in the world that has received US military certification for their finger oximeters.


Turner Medical sells other brands of finger oximeters that have published accuracy claims and proven track records of quality.

We do not sell inaccurate finger oximeters.  We have created a pulse oximeter information page on inaccurate oximeters.  The majority of the finger oximeter brands are from Chinese companies that focus on low prices instead of accuracy and durability.

If you require an oximeter to monitor the health of yourself and/or your patients we highly suggest you research the brand you are purchasing.  There is a significant difference in quality and accuracy.

  1. After I calibrated it to the treadmill, it was telling me that I was running 8:02 or something ridiculous. I knew that wasn't right commercial scale calibration, either, and I don't understand how that happened. I should have just thrown my Garmin across the room and worried about it later, but I was determined to find the right calibration number.
