OSCAR - TriOS Mess- und Datentechnik

Go to content

Online hyperspectral integrating cavity absorption meter.
OSCAR is a new high-end absorption meter, following the principle of the well-known PSICAM (Point Source Integrating Absorption Meter). This principle allows to measure the real absorption spectra without the use of many assumptions, like other instruments on the market. OSCAR is suitable for laboratory use, but also for in situ profiling and moored applications. Internal datalogging function and low power consumption make the sensor suitable for autonomous measurements.
