Oxitest Plus 7

SpO2 Simulator – with Nellcor® Probe

Exclusive Nellcor-Puritan Bennett sensor port
The versatile, handheld Oxitest Plus7 provides the most advanced technology available in the market today for verifying the proper operation and performance of pulse oximeter monitors and modules throughout the clinical environment.

The Oxitest Plus 7 has an exclusive Nellcor-Puritan Bennett sensor port, which was developed in cooperation with Nellcor®. This Industry-exclusive feature allows correct selection of the instrument’s simulation output to the specific R-Cal value of the attached Nellcor® probe.

Compatibility beyond compare
To further enhance your pulse oximeter testing requirements, Oxitest Plus 7 is compatible with the ES601 Plus and other automated test systems such as the Fluke® Biomedical medTester 5000C.

Designed for compatibility with a wide variety of pulse oximeters, the Oxitest Plus 7 is the efficient, cost effective solution to your pulse oximeter testing requirements.
