Oxygen Bomb Calorimeter

(GD-ISO1716, GDY-1A)

Oxygen Bomb Calorimeter


GD-ISO1716 Oxygen Bomb Calorimeter:

Heat of combustion of materials is important characterize parameters to calculated building materials release heat and fire basic data.The GD-ISO 1716 Oxygen bomb calorimeter is designed according to ISO 1716.

GDY-1A Oxygen Bomb Calorimeter:

1.GDY-1A Oxygen Bomb Calorimeter is designed and made as per the National Standard of People’s Republic of China GB/T213 “Test Methods for Calorific Value of coal”, GB/T384 “Test Methods for Calorific Value of Petroleum Products” and Calibration Regulation of People’s Republic of China JJG672 “Oxygen Bomb Calorimeter”, as well as Company Standard of Shanghai Q/YXYY 10 “XRY-1 Series Oxygen Bomb Calorimeter”.

2.The heat capacity of the instrument is 14400~14500 J/K, and 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.


  • ISO 1716 

  • GB/T 14402

  • GB/T8624 


GD-ISO1716 Oxygen Bomb Calorimeter:

1.  GD-ISO 1716 Oxygen Bomb Calorimeter including: calorimeter apparatus, high-pressure oxygen bomb, cold water installations, computer and control system (which can record and display the curve), LCD screen and software.

2.  Crucible made of stainless steel.

3.  Box paint treatment; all internal parts are made of stainless steel, corrosion-resistant, easy to clean.

4.  Ignition wire break is detection, and automatic ignition.

5.  The test procedure automatically turn off.

6.  Test abnormalities has sound alarm.

7.  Computer control system: Control box with USB / RS232 serial port with an external brand desktop or laptop operating control; High degree of automation, test procedure safe and reliable, easy to operate.

GDY-1A Oxygen Bomb Calorimeter:

1) GDY-1A Oxygen Bomb Calorimeter uses a self sealed oxygen bomb, all the structure of the use of stainless steel, the strength is sufficient to withstand the maximum pressure generated by solid combustion (70 ~ 60 ATM), and can withstand the pressure of liquid fuel generated by the greater pressure.
2) The inner tube of the instrument is made by stainless steel sheet, section of pears, put the barrel of water was 3000 grams, water cylinder with electric blender, to ensure that the inner tube water bath temperature uniformity.
3) GDy-1A Oxygen Bomb Calorimeter of the external water jacket is a double container and experiment when filled with water, through the water jacket mixer to cylinder in uniform temperature, formed to meet the test requirements of the constant temperature environment.
