XRY-1A Digital Petroleum Oxygen Bomb CalorimeterDetailed product description：

The XRY-1A digital oxygen bomb calorimeter is designed and manufactured in accordance with the requirements of the national standards GB/T 213 "Determination of Calorific Value of Coal" and GB/T 384 "Determination of Calorific Value of Petroleum Products" of the People's Republic of China, the national metrological verification regulation JJG672 "Oxygen Bomb Calorimeter" of the People's Republic of China, and the Shanghai enterprise standard Q/YXYY 10 "XRY-1 Oxygen Bomb Calorimeter".
The thermal capacity of this instrument is 14000~15000J/℃, suitable for determining the calorific value of non water containing petroleum products (gasoline, jet fuel, diesel, fuel oil, etc.) as well as combustible substances such as coal, coke, paraffin, etc. using the calorimeter oxygen bomb method.

1、 Main technical features
1. The XRY-1A digital oxygen bomb calorimeter adopts a self sealing oxygen bomb, and the entire structure is made of stainless steel. Its strength is sufficient to withstand the maximum pressure generated during solid combustion (60-70 atmospheres), and can withstand even greater pressure generated by liquid fuel.
2. The inner water cylinder of this instrument is made of stainless steel sheet with a pear shaped cross-section. The water cylinder has a water capacity of 3000 grams and is equipped with an electric stirrer to ensure uniform water bath temperature.
3. The outer water jacket of this instrument is a double-layer container, which is filled with water during the experiment. The water jacket stirrer is used to make the temperature inside the cylinder uniform, forming a constant temperature environment that meets the test requirements.
