One of the latest developments of SST is the fast optical oxygen sensor. It
is capable of measuring dissolved oxygen with highest precision. The
measuring principle is based on red light excitation.
Indicators showing
luminescence in the near infrared (NIR), which decreases with increasing oxygen
(quenching effect). The red light excitation significantly reduces
interferences caused by autofluorescence and reduces stress in biological
systems.
The sensor is equipped with an own temperature sensor for internal
calculation and linearization. Due to its analog output it can easily be
connected to SST multiparameter probes as well as to third party
equipment.
