Two, Sable Systems Promethion instruments, one for each chamber. These integrated instruments measure oxygen, carbon dioxide and water vapor pressure within the chambers. This eliminates the need for drying the sample gases.
The control room/subject preperation area. Notice the two separate computers, one for each Promethion integrated instrument. Metabolic studies in both chambers can be run simultaneously.

Schematic of the two chamber whole room indirect calorimeter (WRIC) Laboratory comprising of the 23-hour studies and resting metabolic rate/thermic effect of food (RMR/TEF) chambers.
The 23-hour studies chamber within the HIAS WRIC. It is essentially the size of a small studio apartment with an interior volume of 19,000 liters. This chamber obtains metabolic and macro-nutrient utilization measurements during longer stays up to 23-hours. Notice the cycle ergometer which is used for studies involving exercise protocols.
This is showing the restroom within the 23-hour studies chamber. Notice the grab bar next to the toilet. Furthermore, the chamber doors allowed wheelchair access thus enabling studies involving disabled or senior subjects.
Hangzhou Institute for Advanced Study is part of the Chinese Academy of Sciences. This teaching and research institution promotes the development of innovative and entrepreneurial activities in order to build a Chinese-style, world-class institution.
Exterior and interior of the RMR/TEF chamber. This room has an interior volume of 7,200 liters and contains a comfortable reclining chair. The room also features a toilet and sink for TEF studies lasting several hours. Note the pass thru and the door mounted blood port as shown in the left hand photo.
Fresh air buffer space (opened) and 23-hour studies chamber (closed) doors. Note the pass thru and blood port on the 23-hour studies chamber door.
Fresh air buffer space that supplies both the 23-hour studies and RMR/TEF chambers. Air within this space is maintained at 21 C and a constant relative humidity by the heat pump unit. Finally, notice the air is drawn into both chambers by pipes near floor level. This assures air of consistent composition is fed into the chambers.
