Product details
  • scope of application
  • The fully automatic petroleum product calorific value tester complies with GB/T384 and is suitable for measuring the calorific value of combustible materials such as coal, oil, etc. in industries and departments such as electricity, coal, papermaking, petrochemicals, cement, agriculture and animal husbandry, pharmaceutical research, and teaching.


  • Functional Features
  • 1. The instrument adopts multi probe temperature sensing technology, which automatically adjusts the temperature, accurately quantifies the water volume in the inner cylinder, automatically circulates the water in the inner cylinder, and automatically determines the water level in the outer cylinder. The manual operation only involves weighing the sample and installing the oxygen bomb, while everything else is automatically controlled by the instrument, making it convenient and fast.

    2. Adopting imported pump circulation, the temperature of each point in the entire calorimeter system of the instrument is relatively balanced, ensuring the accuracy of the test results;

    3. Adopting automatic oxygenation and deflation device and oxygen bomb automatic lifting mechanism, there is no need for manual oxygenation and deflation, highly automated, and easy to operate;

    4. The instrument adopts imported insulation materials to isolate the influence of the external environment and eliminate external interference;

    5. Using high-precision probe type electronic measuring cups, there is no need for manual weighing of water weight, and the water volume in the inner cylinder is automatically measured. Repetitive error<0.5g, more accurate water volume, shorter test time, fast and accurate, simple and convenient operation;

    6. By using a specially designed oxygen bomb from Fulande, the phenomenon of poor contact of the ignition wire, which leads to abnormal testing, can be pre treated to improve work efficiency.;

    7. Can access laboratory management system, backup and upload test results;

    8. For solid waste samples, special oxygen bombs, crucibles, and other accessories can be selected;

    9. Optional oxygen bomb gas collection device for gas collection inside the oxygen bomb.
