Introduction
This instrument is designed and manufactured according to the requirements of the national standard GB/T 213-2008 “Method for Determination of calorific Value of Coal”, GB/T 384-1988 “Method for determination of calorific Value of Petroleum Products” and the national metrological verification regulation JJG 672-2001 “Oxygen bomb calorimeter” of the People’s Republic of China. Suitable for the determination of non-aqueous petroleum products (gasoline, jet fuel, diesel and fuel oil, etc.) as well as coal, coke, paraffin and other combustible substances, the determination of heat, is an automatic, efficient, safe, high test accuracy, fast test speed, easy to use high-grade instrument
Main technical features
1, the use of single-chip microcomputer control technology, color LCD display, high-precision temperature sensor and high-performance A/D conversion device, composed of high degree of automation, video effect is good, easy to use, convenient data arrangement intelligent instrument.
2, the test process is fully automated, after the sample is put, input a variety of correct parameters, no manual intervention is automatically completed each test process, after the test can be directly printed measurement data.
3, the use of self-sealing oxygen bomb, all the structure is made of stainless steel, the strength is enough to withstand the water pressure test of 20MPa at room temperature.
4, the inner water cylinder is made of stainless steel sheet, the cross section is pear line, the water cylinder is loaded with 3000 grams of water, the water cylinder is equipped with an electric stirrer to ensure that the temperature of the water bath in the inner water cylinder is uniform.
5, the outer water jacket is a double-layer container, the experiment is filled with water, through the water jacket agitator to make the water temperature in the cylinder uniform, forming a constant temperature environment to meet the test requirements.
