Calorific value combustible substance detector (calorimeter) for the determination of liquid oil, heavy oil, crude oil, light oil, kerosene, diesel, solid biomass fuel, wood, sawdust, wood chips, wood coal, pine fir, roots, Coke board bamboo, wood processing waste, coal, coke, coal, slag, fly ash, wood pellets, ethanol, methanol, fertilizers and raw materials such as adobe brick measuring non-flammable material. The scope of application of automatic calorimeter measurement automatic calorimeter coal, coke, petroleum, cement for measuring electric power, coal, metallurgy, petrochemical, quality control, environmental protection, cement, paper, Geological Prospecting, research centers and other sectors heat raw materials, brick and other solid or liquid fuel, in line with the national standard GB / T213-2008 "Determination of calorific value of coal method" requirements. Instrument features automatic calorimeter 1 by the MCU control, with LCD color display, Chinese display. 2 high degree of automation, automatic weighing heavy water and automatically adjust the temperature inside and outside the barrel, manual operation only weighed sample of the input sample weight value, other fully done automatically by the instrument, and print test results, character print results at a glance. Quick and easy. 3 test results are stable and reliable, it can be used as arbitration analysis. 4 rational structure, reliable performance, low failure rate, easy to use. 5. Versatility: A lower heat has made software, such as feed, food, cement raw materials, brick and other low heat flammable substances. Automatic calorimeter technical indicators and parameters Temperature range: 5-40 ℃ temperature Resolution: 0.0001k precision: ≤0.1% thermal capacity: about 10450J / K Power supply voltage: AC220V 50Hz Weight: about 40kg single sample test time : 15min about
