• Tests can be run at the exact Thermal inertiaThe thermal inertia is equivalent to the  PHI-factor. Both describe the ratio of mass and specific heat capacity of a sample or sample mixture compared to that of the vessel or sample container.thermal inertia at which they will run in the plant or storage container.
• Kinetics that are dependent on Thermal inertiaThe thermal inertia is equivalent to the  PHI-factor. Both describe the ratio of mass and specific heat capacity of a sample or sample mixture compared to that of the vessel or sample container.thermal inertia, such as competing reactions that cannot be compensated for mathematically, are no longer a problem.
• Thermal inertiaThe thermal inertia is equivalent to the  PHI-factor. Both describe the ratio of mass and specific heat capacity of a sample or sample mixture compared to that of the vessel or sample container.Thermal inertia can be corrected without having to extrapolate kinetics from overlapping and multiple reactions.
• Data obtained will directly correspond to actual run or storage conditions making it easier to relay the information to non-calorimetry specialists.

NETZSCH Proteus^® Measurement software: Proven Technology Leader

• Data is automatically saved to hard-drive throughout the run
• Intelligent Firmware monitors the status and health of key operating sensors and active components
• Safety integrated with hardware and firmware controls
• Seamless integration of data files to Proteus^® Analysis, NETZSCH Advanced Software Tools or 3^rd party software

Accelerating Rate Calorimeters can be used for the thermal analysis of solid or liquid chemicals or for gas/liquid, liquid/liquid, gas/solid, and liquid/solid mixtures. They can also be used for process simulation of batch and semi-batch reactions, fire exposures, emergency relief venting, and physical properties measurement.
