They are not barometers but they do have an aneroid type, in which the covering is a hollow, cylindrical block of metal with a top and bottom.  
They are not barometers but they do have an aneroid type, in which the covering is a hollow, cylindrical block of metal with a top and bottom.  All of them contain this covering, or jacket, that can be used to control thermal exchange between them and the environment.  Nonisothermal ones yield evaluations based on the temperature changes they produce, though isothermal ones are easier to use and include the well-known bomb variety.  FTP, name these devices that are used to measure the quantity of heat involved in various chemical processes.
