Performance Characteristics: 

Utilizes microcomputer control, retaining all computer functions and compatibility with various general-purpose software. Automatically calibrates the heat capacity of the calorimetric system and measures calorific value. By inputting data such as sulfur, moisture, and hydrogen content, it converts and prints results including bomb calorific value, gross calorific value, and net calorific value. 

1. The inner bucket does not need to be removed; operation is simple and maintenance is convenient. The single-head oxygen bomb uses a sleeve pressure method to secure the ignition wire, ensuring convenience, safety, and reliability. 

2. Features a large-capacity outer barrel water tank with cooling function to ensure stable heat capacity, suitable for long-term continuous sample testing. Employs a modular micro-circulation water cooling system that adjusts heat dissipation based on previous calorific value measurements, balancing the inner barrel water temperature to maintain relative consistency with the outer barrel water temperature. This reduces environmental impact on testing accuracy, enables continuous experimentation, and addresses the common issues of complex maintenance, frequent failures, and the need for professional repairs associated with traditional compressor-cooled fully automatic calorimeters. This saves customers significant time and makes the testing process simpler and more comfortable. 

3. Designed with a precise inner barrel water quantification system, featuring automatic water injection and drainage control. Water injection is highly accurate, and drainage is thorough, ensuring consistent inner barrel water volume for each test and effectively guaranteeing measurement precision. 

4. Incorporates water purification technology to enhance instrument reliability. 

5. Includes functions such as high and low position conversion, benchmark conversion, parallel sample testing, automatic heat capacity calculation, and manual recalculation. 

6. Equipped with smart terminal functionality, offering multiple network access methods. Combined with a data interaction center, it enables data sharing and real-time data upload to management systems. 

7. Some components use imported parts, including high-precision temperature sensors with a temperature resolution of 0.0001K, ensuring overall integrated circuit stability and reliability. 

8. Utilizes power inverter and purification technology, making instrument operation unaffected by external voltage fluctuations or grid instability. 

9. The inner and outer barrel water systems are independent and do not interfere with each other. 

10. The oxygen bomb is made of heat-resistant and corrosion-resistant nickel-chromium alloy steel, providing faster heat transfer. 

11. Fast testing speed with all data measured directly, ensuring authenticity and reliability. No software correction is used to alter test results. 

12. Employs serial port technology to adapt to new developments in computer technology, enabling one machine to control multiple units without interference between tests. Data processing can be performed simultaneously during experiments, facilitating user data queries. 

13. The testing software supports the Windows 7 platform with high stability and can be networked for remote data sharing. 

14. Strong environmental adaptability, with precision, accuracy, and stability meeting national standard requirements.
