Oxymax Calorimetric Assessment - Columbus Instruments Oxymax system is the leading open circuit indirect calorimeter for lab animal research. Heat is derived by assessment of the exchange of oxygen for carbon dioxide that occurs during the metabolic process. The relationship between the volume of gas consumed (oxygen) and of that produced (carbon dioxide) reveals the energy content of the foodstuff utilized by the subject. This 'calorific value' is then applied to the volume of gases exchanged to compute heat.
Oxymax Sensor Technologies:
Paramagnetic O2 Sensor - Included as standard, measurement range is 0-100% with a response time of 90 seconds per cage.
Zirconia O2 Sensor - Part of the "High Speed Sensing Option", measurement range is 0-100% and when coupled with our dual tube High Speed Gas Dryer, response time is 20 seconds per cage. Multiple High Speed Sensor sets can be connected to the system to allow 2 or more cages to be measured simultaneously.
