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 Datrend's 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.

enclosure (total 5) from:
Datex, Hewlett Packard, Novamatrix, Spacelabs, Invivo,
Datascope, Criticare, Critikon, Sensormetics, PhysioControl,
Simed and Nihon Koden.
Alarm Tests:
Five automated test sequences for determining oximeter alarm response time to Low SpO2 ; Low Heart Rate; High Heart Rate; Low Perfusion; and Motion Artifact conditions.
Also determines time required for oximeter alarm to self-clear after test conditions are returned to normal.
Alarm Test parameters may be user-programmed via the RS-232 port.
Auto Preset and Alarm Test results saved in battery-backed, non-volatile Memory, along with up to 20 PASS/FAIL records from manually-conducted tests. Test results in Memory may be printed as a Test Report via optional external Printer, or may be downloaded via RS-232 port to personal computer or automated tester.
