Oxygen Bomb Calorimeter

Summary

The instrument is designed and made as per GB/T213 “Test Methods for Calorific Value of Coal”, GB/T384 “Test Methods for Calorific Value of Petroleum Products” and Calibration and Inspection Regulation of People’s Republic of China JJG672 “Oxygen Bomb Calorimeter”, as well as the Company Standard of Shanghai Q/VCZK 10 “XRY series Oxygen Bomb Calorimeter”.

The instrument is controlled by computer, automatically finish the combustible material calorific value measurement, and it is intelligent and automatic, can be widely used to determine calorific value of combustible substance such as coal, oil, coke and paraffin, etc. It is the best choice of companies in the field of thermoelectricity, smelt, cement, chemical, and scientific research institutes, and institutions of higher learning.

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

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

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

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

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

7. The electronic balance with communication function to share the data by the internet. (Optional)
