Automatic calorimeter (Isoperibol)is a CE certified,long-lasting instrument for measuring calorific value of combustible materials and finds its applicability in electrical,coal,papermaking,petrochemical,cement,farming industry and medical research.It works in temperature range of 5℃-40℃ showing resolution of 0.0001℃ & precision of RSD≤0.1%.With a weight of 55 kg and dimension of 630mm×420mm×450 mm it gives results in just 8 minutes.Works at 220V supply(50/60HZ) and Power≤1.5KW. It can automatically determine refrigerating capacity and balance circulation system owing to its semi-conductor water refrigeration system,hence water temperature remains constant and environmental influence is reduced.Tests can be made continuously and no need to measure water and adjust water temperature.
