Oxygen bomb calorimeters measure the heat of chemical reactions or physical changes. This is done by performing the reaction in a container that maintains constant volume and they are thus designed to withstand the pressure that builds up as the reaction occurs. In an oxygen bomb calorimeter, the sample is loaded in the reaction chamber (called the bomb) along with oxygen; this is submerged in water within an insulating container. Once the sample is ignited, a thermometer which is partially submerged in the water, records the temperature changes that occur. Level of precision, capacity, and price are important considerations when purchasing a bomb calorimeter.

The AC500 has an integral water-measuring and combustion vessel-filling station that simplifies sample preparation, without additional heaters or coolers. An electronic thermometer accurate to 0.0001°C measures the temperature of the water every six seconds. The AC500 also has the unique ability to constantly monitor temperature in both the outer jacket and the calorimeter proper, making two-channel correction possible.
