Oxygen Bomb Calorimeter

The instrument is designed and made according to GB/T213-2008 Method for the determination of the calorific value of coal, GB/T384-1988 Method for the determination of the heat value of petroleum products and Calibration and Inspection Regulation of People’s Republic of China JJG672-2001 Oxygen Bomb Calorimeter. It is suitable for the determination of water-free oil products (gasoline, jet fuel, diesel oil and fuel oil, etc.) and combustible material such as coal, coke, paraffin wax content determination of calorific value. It is a high-grade instrument with the advantages of automatic, efficient, safe, high precision, fast test speed and easy to use.

I. Main technical features

1. The instrument adopts technology of single chip machine, LCD screen, high accuracy temperature sensor and high-performance A/D conversion device. It is a highly intelligent instrument.

2. The test procedure is fully automatic. After placing the sample and inputting the right parameters, the instrument will finish all the procedures without manual interference. It will print the test data directly after test is over.

3. This instrument adopts sealed oxygen bomb. The whole structure adopts stainless steel material. The strength is enough to resist 20MPa hydrostatic test under room temperature.

4. The inner water container is made of stainless steel and the section likes as a pear. Its water volume is 3000g and with electric stirrer to make sure the uniform temperature in water bath.

5. The external water jacket is a double container. It will be filled fully with water when testing, and the stirrer in the water jacket will work to ensure the uniform temperature and create the constant temperature condition for test requirement.
