These Accelerating Rate Calorimeters 244 are designed to safely measure the amount and rate of heat release associated with the processing or storage of chemicals. We are aware of the fact that information is vital in developing and evaluating processes to ensure safe operation and to prevent thermal runaway which can have devastating effects. Thus; we have designed Accelerating Rate Calorimeter 244 technology which is integral to designing inherently safer batteries as well as measuring energetic materials used in such products as propellants, and air bags.
