Overview of SS600 Odor Laboratory:

Scentroid SS600 Odor Laboratory is the world’s most advanced stationary, dynamic, and fully automated olfactometer. It is capable of odor / odour measurement and analysis to all international olfactometry standards. To reduce testing time and ensure maximum lab efficiency the SS600 Odor Laboratory features 6 identical panellist stations for simultaneous odor / odour analysis. Each station is equipped with a Siemens touch screen for flexibility and ease of operation. Three (3) stainless steel sniffing ports at each station allow for true triangular odor / odour analysis.

The Siemens industrial control panel monitors and adjusts test parameters automatically to ensure optimal test conditions. Test results are instantaneously processed and displayed live to the test administrator on the dedicated 8″ touch-screen interface.
