Automatic Calorimeter
Automatic Calorimeter
Description
The K88990 features a removable pressure vessel and bucket design. It can achieve the highest level of precision and accuracy of any oxygen pressure vessel calorimeter. It is a good choice for high precision quality control work and for research and development.
Multiple pressure vessel choices are also available, expanding its functionality for higher energy releases. An isoperibolic calorimeter is one where the surrounding jacket is maintained at a constant temperature while the temperature of the pressure vessel and bucket rise as heat is released by the combustion.
The K88900 and K88990 calorimeters are true isoperibolic calorimeters. In these implementations, a controlled temperature jacket completely surrounds the combustion pressure vessel and its “bucket”. A microprocessor-based controller monitors both the temperature of the bucket and the jacket and performs the necessary heat leak corrections that result from differences in these two temperatures
