Accelerating Rate Calorimeter 244 (ARC®)
The cost‐effective ARC® 244 is designed to safely measure the amount and rate of heat release associated with the processing or storage of chemicals within a container volume between 1.5 ml and 8.5 ml.
Accelerating Rate Calorimeter 254 (ARC®)
The Accelerating Rate Calorimeter 254 (ARC®) provides AdiabatiqueAdiabatic describes a system or measurement mode without any heat exchange with the surroundings. This mode can be realized using a calorimeter device according to the method of accelerating rate calorimetry (ARC). The main purpose of such a device is to study scenarios and thermal runaway reactions. A short description of the adiabatic mode is “no heat in – no heat out”.adiabatic calorimetry data in a safe, controlled laboratory environment.
This information helps provide a sound understanding of the fundamental physical processes involved. From this understanding, various safe operating systems and procedures can be developed to mitigate the hazards posed by a reactive system.
