XRY-1C Automatic Oxygen Bomb Calorimeter is made following national and international standards.
It features semiconductor refrigeration for stable water temperature control, automatic water measurement with low error, and ignition filament detection.
With a standard pipeline design for high – precision results, it also has a convenient drainage system. It has an electronic balance for data sharing.
Technical specifications: power supply AC (220±10%)V, 50Hz; measuring temp. range 5℃ – 35℃; RSD ≤40J/K; test time about 12 min. Ideal for coal and petroleum heat value tests.
Summary
The instrument is designed and made as per the National Standard of People’s Republic of China GB/T213-2008 and ASTM D240 Test Method for Calorific Value of coal, GB/T384-1988 Test Method for Calorific Value of Petroleum Products and Calibration Regulation of People’s Republic of China JJG672 Oxygen Bomb Calorimeter
I. Main technical features
1. 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 longtime test requirement, and make sure the test result is correct.
2. 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
3. Automatically detecting the resistance of ignition filament, automatically checking the installing condition of ignition filament before test.
4. Standard pipeline design, vastly shortening the pipeline, and more reasonable pipeline design to ensure more precision of test results.
5. Adopting professional discharge water ports, more convenient and faster when the instrument drains away water or change the water.
6. The electronic balance with communication function to share the data by the internet.
