The Lightman is unique, it performs a vital job that no
simulator or other sensor tester can do.
The Lightman SpO2 Sensor Tester
is a micro spectrometer. It tests the most vulnerable part of the oximeter
system - the sensor LEDs. It is the only device on the market today that
tests LED wavelength accuracy.
It tests LED wavelength accuracy,
intensity, incipient failure, and any wavelength drift. Additionally, the
Lightman tests photodiode sensitivity and for intermittent cable breaks. A
change in any of these can cause pulse oximeter testers to become in accurate.
