The quality of indoor air is strongly influenced by volatile organic compounds (VOCs) released from materials and products, including construction and building products, such as adhesives, furniture, paints, and many more.

The Olfasense VOC emission test chamber EK250B allows characterization of the emissions of volatile organic compounds under precise test conditions, and is fully compliant with the requirements of ISO 16000-9, EN 16516, EN 717-1, and GEV Testing Method.

Our chambers have been developed in close cooperation with experts from industry and research, and can be used for a broad analytical performance spectrum via 4 sample ports.

We invite you to use our laboratory showroom for a trial run, to perform your own tests and experience our chambers at first hand. Our Olfasense engineers will gladly assist you with your individual trial run.
