Most pulse oximeters are made for one finger size. They are either too loose or too tight. INV-430J employs an innovative self-adjusting spring system to fit your finger snugly into the chamber without impeding blood flow.
The Innovo INV-430J uses medical grade, soft hypoallergenic silicon in the finger chamber, providing unparalleled comfort to your finger. It is also outfitted with filtered glass to reduce eye fatigue.
Last and not least, the Innovo INV-430J is made up of solid ABS plastic to absorb and shield environmental infra-red from the sensor. This increases the signal to noise ratio and the accuracy of the measurement dramatically. We are so sure you will like it that we are backing the INV-430J with a LIFETIME HASSLE FREE PRODUCT REPLACEMENT guarantee.
