Performance characteristics:

1. Quantitative measurement with measuring cup, accurate water quantification; The inner bucket does not need to be raised, is easy to operate, and is easy to maintain. Single head oxygen bomb, equipped with a compression method to secure the ignition wire, convenient, safe and reliable.

2. Large capacity outer cylinder water tank and backup water tank, with cooling function, ensure stable thermal capacity, and adapt to long-term continuous sampling; Adopting a modular microcirculation water cooling system, the heat dissipation can be determined based on the previous heat generation, balancing the inner cylinder water temperature to maintain a relatively constant temperature with the outer cylinder water temperature, reducing the impact of the environment on testing accuracy, and enabling continuous experiments. This solves the common problem of complex maintenance, frequent malfunctions, and the need for professional maintenance of compressor refrigeration fully automatic calorimeters in the past, saving customers a lot of time and making the testing process simpler and more comfortable.

3. Design a unique precise quantitative system for inner cylinder water, with automatic control of water injection and drainage. The water injection volume is highly accurate and the drainage is clean, ensuring consistent water volume in each inner cylinder and effectively ensuring the measurement accuracy of the system.

4. Using patented technology to achieve water purification and improve the reliability of instruments;

5. Equipped with high and low positions, benchmark conversion, parallel samples, automatic calculation of heat capacity

Functions such as manual recalculation;

6. Equipped with intelligent terminal functions, providing multiple network access methods, combined with data

According to the interaction center, data sharing is achieved and real-time data is uploaded to the management system.

7. Some components are imported, including precision temperature probes with temperature resolution

Reaching 0.0001K; making the overall integrated circuit more stable and reliable.

8. By adopting power inverter and purification technology, the instrument operates without being affected by external voltage or grid waves

Dynamic impact.

9. The inner and outer bucket water systems are independent of each other and do not affect each other.

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

11. Fast testing speed, all data tested, true and reliable, no software correction is used to change the test results.
