Modern-day ones use thermocouples or thermistors as their measuring devices.
One type of this device used in the CMS experiments of the Large Hadron Collider consists of a barrel with two endcaps and utilizes lead tungstate to determine particle energies. Another of these devices, named for Joly, consists of two spherical containers in a steam bath and measures how much condensation appears on each container. Modern-day ones use thermocouples or thermistors as their measuring devices. Yet another type of this device that maintains constant volume to eliminate PV work determines a sample's heat of combustion. That is known as the "bomb" type. For 10 points, name this instrument that can measure the heat given off in a reaction or the specific heat of a sample.
