Automatic Oxygen Bomb Calorimeter PRY-1C

Model: PRY-1C

TOP INSTRUMENT Automatic Oxygen Bomb Calorimeter is a device that measures the heat of combustion of a substance by igniting it in a high-pressure oxygen environment. It is suitable to determine calorific value of combustible materials such as petroleum products without water (gasoline, jet fuels, diesel oil and fuel oils, etc.), coal, coke and paraffin, etc.

  • PRY-1C

  • TOP


  • Adopting semiconductor refrigeration to decide the refrigerating capacity according to the calorific value,the instrument can automatically adjust water temperature and keep water in a relative constant temperature range,realize the continuously and long time test requirement,and make sure the test result is correct.

  • Using USB port,convenient to connect.One computer can control many sets of Oxygen Bomb Calorimeter.

  • With a electronic measuring cup itself,no need to weigh the water by manual,it can measure the water volume automatically,the repetitive error<0.4g

  • Automatically detecting the resistance of ignition filament,automatically checking the installing condition of ignition filament before test.

  • Standard pipeline design,vastly shortening the pipeline,and more reasonable pipeline design to ensure more precision of test results.

  • Adopting professional discharge water ports,more convenient and fast when the  instrument drains away water or change the water.

  • The electronic balance with communication function to share the data by the internet.
