The indirect calorimetry systém Phenomaster utilises measurements in a closed chamber through which a constant amount of air passes and can be controlled over a set temperature range (6-35°C). The animal is placed in the chamber where it consumes oxygen and produces carbon dioxide depending on its metabolic activity. The difference in gas concentration between entering and leaving the chamber is monitored and used as a basis for calculating the respiratory coefficient and energy expenditure. The system’s functionality extends beyond the scope of direct calorimetry, encompassing the capacity to monitor food intake, physical activity, and telemetric evaluation of body temperature. The system can also be adapted for measurement on rats.
Notable features:
– The system has been designed to measure energy metabolism, body core temperature, food intake and animal activity. The integration of all data into a unified output file facilitates comprehensive analysis.
– The system has a highly accurate time resolution in the measuring chamber over a substantial temperature range (6 – 35 °C).
– The system is characterised by its user-friendly interface, which facilitates comprehensive control and data visualisation.
– The system can been adapted to measure energy expenditure during voluntary or forced physical activity.
– The animal can be acclimated to the environment, thereby minimising the effect of stress on the measured values.
