XRY-1A+ type petroleum oxygen bomb calorimeterDetailed product description：

The XRY-1A+oxygen bomb calorimeter is designed and manufactured in accordance with the requirements of the national standards GB/T 213-2008 "Determination of Calorific Value of Coal" and GB/T 384-1988 "Determination of Calorific Value of Petroleum Products" of the People's Republic of China, as well as the national metrological verification regulation JJG 672-2001 "Oxygen Bomb Calorimeter" of the People's Republic of China. It is suitable for measuring the calorific value of petroleum products (gasoline, jet fuel, diesel, fuel oil, etc.) that do not contain water, as well as combustible substances such as coal, coke, paraffin, etc. It is an automatic, efficient, safe, high testing accuracy, fast testing speed, and convenient to use high-end instrument.

1、 Main technical features
1. The XRY-1A+petroleum oxygen bomb calorimeter adopts microcontroller control technology, color LCD screen display, high-precision temperature sensor, and high-performance A/D conversion device, forming an intelligent instrument with high automation, good video effect, easy use, and convenient data organization.
2. The testing process of this instrument is fully automated. After the sample is placed, various correct parameters are inputted, and each testing process is automatically completed without manual intervention. After the test is completed, the measurement data can be directly printed.
3. This instrument adopts a self sealing oxygen bomb, and the entire structure is made of stainless steel, with sufficient strength to withstand a water pressure test of 20MPa at room temperature.
4. 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.
5. 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.
