SC300P Scientific Olfactometer Overview:

Scentroid SC300P ( Scientific Olfactometer ) is a specialized multi-sensory olfactometer with EEG and FNIR capabilities for advanced psychological and physiological research and treatment. The SC300-P has been used by researchers and doctors to treat a variety of disorders including post-traumatic stress disorder.

The SC300P (Scientific Olfactometer with EEG Capabilities) is more than just an olfactometer, but a true multi-sensory stimuli instrument. Up to 8 odours can be connected to the instrument and programmed to be administered to the panellist at various concentrations. Images, videos, and audio stimuli can be simultaneously administered by the SC300P (Scientific Olfactometer with EEG Capabilities) via its external monitor to provide complete sensory immersion.
