Patented Control Algorithm
A unique control algorithm (Patent Pending) optimizes performance and dilution accuracy while minimizing sample consumption
Unprecedented Dilution Range
Dilution range of 8-131,072 (2^3 – 2^17) with variable step size to a max. of 1000 steps in-between surpasses any other commercially available mobile olfactometer
International Standards
Adheres to all international olfactometry standards: EN13725:2003, ASTM E679-04, NVN2820, VDI 3881, GB/T14675-93
Deployment simply requires connecting the power cord to a standard 120/240 VAC outlet and connecting the air supply hose
Overview
Scentroid’s SC300 Portable Olfactometer is the world’s most advanced mobile olfactometer. It allows for a full odour lab to be deployed anywhere in a matter of minutes. There is no need for dedicated lab space – Simply plug in the SC300 and start analyzing odours to all international standards. The SC300 can perform any odour test mode you require including a true 3 port triangular forced-choice as well as binary, hedonic tone, and direct presentation.
SC300 Portable Olfactometer Compressed Air System
The compressed air is passed through a cooling system to prevent overheating after prolonged use. Fans are used on either side of the container to ensure air is passing through, allowing the air supply to work while the lid is closed. A final gauge is used to regulate the airflow being used and is ideally set at 80 psi. The final step is to attach the product to the outlet and turn on the main switch.
SC300 Portable Olfactometer Deployment
Deployment only requires connecting the power cord to a standard 120/240 VAC outlet and connecting the pneumatic hose between the air supply subsystem and the control subsystem. The air sub-system provides clean air regardless of ambient air through its incorporated oil-free pump, HEPA filter, carbon filter, no-maintenance membrane air dryer, and regulator. The test administrator can then view live results, analyze data, and control the test using the dedicated admin. station with the included Siemens 8” touch screen.
Scentroid Mobile Air Supplier
The Scentroid Mobile Air Supply is designed to provide compressed air supply for a variety of Scentroid products out in the field. This is ideal due to the fact that it produces no oil in the airflow, and therefore can be used as an independent air supply when the oil in the airflow is often an issue. The compressed air from the tank is monitored from the pressure meter, and if it rises more than 8 bar (approximately 116 psi) the tank will automatically cut off the pressure control switch. When the pressure inside the tank lowers to 6 bar (approximately 87 psi) then the power is turned back on.
