The Dynamic Dilution Olfactometer quantifies odors using a panel.

  • Odor concentration & odor perception threshold determination with triangular choice, yes & no or blind methods.
  • Evaluation of the odor relative intensity level, hedonic tone or individual appreciation on a 1 to 10 scale. Pure or known dilution levels can be used to determine the evolution of perception with dilution.
  • Odor intensity determination with comparison to a reference gas (n-butanol). This task can be done by using pure or known dilution levels to determine the evolution of the intensity with dilution.
  • Panel calibration with n-butanol.

The system

ODILE™ is composed of several units: dilution unit, operating system software, odor station, air purification system and pressurized vessel.

ODILE™ includes operating system software running on Microsoft Windows 95, 98, 2000 or NT for electronic control of the unit.
