More reliable data and a wider range of application due to the fastest tracking rate up to 200 K/min
Patented VariPhi® technology can realize low phi test even with a small and safe sample size. Effective detection of both exothermic and endothermic transitions and sample Cp can be achieved by the versatile operating modes on ARC® 254
Controlled by the same powerful Proteus® software which user can use to operate all other NETZSCH thermal analysis instruments in the lab.
The Accelerating Rate Calorimeter 254 (ARC® 254) provides 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.
The Accelerating Rate Calorimeter 254 (ARC® 254) simultaneously measures temperature and pressure. The sealed pressure system also allows the user to evaluate the effect of different gas atmospheres on the thermal stability of the system.
Gaseous reaction products may be analyzed at the end of an experiment to help identify and understand the reaction mechanisms involved.
The Accelerating Rate Calorimeter 254 (ARC® 254) is designed to model the course of a large-scale reaction on a small scale. A test material is externally heated in a fixed volume until exothermic activity is detected. Keeping that sample in an adiabatic environment where no energy is lost, the calorimeter then measures and records the sample temperature and pressure.
