The XRY-1A+ Oxygen Bomb Calorimeter is designed and manufactured in accordance with the national standards GB/T213 "Method for Determination of Calorific Value of Coal," GB/T384 "Method for Determination of Calorific Value of Petroleum Products," and the national metrological verification regulation JJG672 "Oxygen Bomb Calorimeter." It can test the calorific value of various combustible solids or liquids without restrictions on high or low calorific values. It exclusively adopts a three-tank circulating water system, enabling continuous 24-hour uninterrupted testing of samples with accurate and intuitive information. This instrument is widely used for measuring the calorific value of combustible materials such as coal, oil, coke, paraffin, plants, and garbage, making it an ideal choice for thermal power, metallurgy, cement, petrochemical industries, as well as relevant research institutions and universities.

I. Performance Features:1. Professionally designed 4-layer printed circuit board and surface-mount technology enhance the instrument's stability and anti-interference capability. 2. Unique ultra-high-bit analog-to-digital conversion technology: Utilizes imported 24-bit high-precision, high-stability analog-to-digital converters from the United States for temperature measurement, ensuring higher accuracy and precision. 3. Sensor probes employ high-precision, high-stability thin-film platinum resistors imported from Germany, fully armored with silver tubes. 4. Full Windows interface: Adopts the most advanced object-oriented software design technology, allowing multiple intelligent analytical instruments to be connected to form an analytical system. 5. Advanced serial bus technology: The instrument uses the advanced serial R485 bus, which can be connected to a computer via a two-core data communication cable, fully enabling one computer to control multiple analytical instruments. 6. Innovative water volume constant compensation technology significantly improves measurement accuracy. 7. Precise refrigeration technology: The instrument employs the domestically advanced "circulating water cooling technology" to quickly return the water temperature to the initial value, ensuring testing precision. 8. The water capacity in the calorimetric bucket exceeds 60 KG, and the water circulation system uses two high-power magnetic pumps imported from Germany, with no solenoid valves and low failure rates, making it one of the most superior performance instruments in the domestic market. 9. Suitable for low calorific value material testing, employing a unique non-fusing ignition method to ensure successful ignition every time. 10. Equipped with an LCD screen for convenient reading.
