Calorimeters are important because they help measure the heat and monitor the temperatures of chemical reactions. The bomb calorimeter has high level of automation which can be used in many applications. All the needed process excluding the sample preparation for determining the GCV of a solid or liquid sample can be done by the calorimeter. A single bomb covers the GCV as low as 375 kcal/kg and as high as 12000 kcal/kg. The bombs available are normal bomb and special halogen-resistant bombs.
