Performance Features

Highly adaptable to various environments, with precise, accurate, and stable testing results.

① Unique spiral tube isothermal system design creates a controllable and stable internal environment for instrument experiments (consisting of an outer drum and lid, with temperature difference < 0.05℃), effectively blocking the impact of the external environment (such as air flow, temperature, etc.) on the inner drum; the water temperature in the outer drum fluctuates less than 0.05℃ throughout the day, and less than 0.01℃ during single sample testing, ensuring accurate and reliable test results.

② The outer drum utilizes semiconductor temperature control technology, balancing both cooling and heating functions without the need for additional cold water to lower the temperature. It ensures the independence of the water systems between the inner and outer drums. After the experiment, the water in the inner drum is directly returned to the water tank. The inflow and outflow of water from the inner drum have no effect on the water temperature of the outer drum, further ensuring the stability of the outer drum's temperature control.

③ Utilizing a constant-volume oxygen bomb, the volume remains steady and unaffected by the operator, eliminating any changes in the inner bucket water level due to oxygen bomb volume variations, resulting in a more stable heat capacity.

④ Features automatic pipeline flushing and water change function to ensure long-term stability of heat capacity.

2. User-friendly design, high level of automation, and rapid testing speed.

①An innovative outer drum water circulation system, a new type of stainless steel oxygen bomb with an easier disassembly design, combined with a quick and direct volumetric determination using a metal inner drum, supplemented by an efficient and stable new inner drum stirring method; ②The oxygen bomb has a faster heat transfer speed, effectively shortening the testing time, with a single sample testing time of ≤14 minutes for continuous testing.

③ Equipped with a constant temperature water tank featuring semiconductor temperature control, it combines cooling and heating functions. Compared to conventional compressor-based chilled water tanks, it offers more precise water temperature control, lower overall power consumption, and reduced noise levels.

3. Data is authentic and reliable.

All data is measured directly, ensuring authenticity and objectivity. No software correction is used to alter test results or compile data.

4. Reasonably structured, stable and safe operation.

Features self-diagnostic capabilities for easy daily maintenance.

Equipped with a unique crucible holder, easy to pick up and put down.

5. Supports both filament and cotton thread ignition methods.

6. Robust data processing, reporting, and printing capabilities, with network and scale connectivity.
