Room Calorimetry

Whole-body room calorimeter

Room calorimeters are an invaluable, powerful tool in metabolic research studies. By using indirect calorimetry the research possibilities increase immensely in a wide range of clinical and research settings. These systems allow long term measurements (up to 7 days), without the limitations of a canopy or a face mask. They allow researchers to gain new insights in the dynamics of human energy expenditure, substrate oxidation and so much more. A room calorimeter allows studying a person’s energy metabolism over longer durations under different circumstances. The systems consist of three different parts: the room itself, climate/circulation control and an analysis unit: the Omnical metabolic system. Fresh air is pulled through the room and both the in- and outgoing air is analyzed. This allows free movement of the test subject in a highly controlled environment. Study duration can vary from 2 hours to over 7 days, while fully controlling the environment (temperature, humidity, light, etc), diet, circadian rhythm, exercise protocols etc. Additional equipment and sensors can be easily integrated to widen the possibilities even more.

The Basic Room Calorimeter is the latest technology in the market and it is a powerful tool that can be used in metabolic research studies. With an experience of over 35 years, we make research more attainable with its portable room calorimeter which can be installed in only a few hours. The BASE room calorimeter allows indirect calorimetry measurements without wearing a face mask or ventilated hood. 

The Room Calorimeter ELEMENTS covers all the necessary utilities to conduct tightly controlled energy expenditure and metabolic research studies. This system comes with optimal subject comfort and total system control. Our experts help you configure the right setup to get you up to speed with room calorimeter research. The system is modular and can be upgraded to suit future study needs. 

The Room Calorimeter ADVANCE offers the highest validated accuracy and reproducability in the market. Designed on a system level out of the highest quaility components, this is the gold standard for energy expenditure studies of any kind; 24-hr energy expenditure, high intensity exercise testing and many more. Validated and applied in 100’s of research studies.
