The calorimeter is one kind of survey quantity of heat and so on instrument.It is (or aluminum) the nature small tube is composed of the outer sleeve and the copper,the small tube's base with the small support which does not transfer heat supports,the small tube places on the big tube's bust peg,moreover between the big and small tube has the crevice,the support and the big tube selects the hot not good conductor,like this may prevent the heat conduction radiation.Fastens down the tube lid may prevent the radiating.During two casings is the air which is not easy to transfer heat,in outer sleeve's cover,generally makes with the lumber,its heat transfer efficiency is low.Covers has two eyelets,inserts the thermometer,another inserts the agitator,the agitator uses for to cause in the investment water testing (known its quality and temperature) exchanges rapidly with the water temperature,but after the thermometer uses for to measure in the small tube the known quality water initial temperature and the mix temperature.During two casings does not contact prevents the hot transmission
