ASTM D240 Microcomputer Automatic Calorimeter TP-5000C

  • TP-5000C


Product Description



1.It is mainly composed of thermostatic calorimeter system and single-chip microcomputer control system. It is a type of highly automated calorimeter that is automatically controlled by a single-chip microcomputer system, capable of data processing.

2.The instrument is mainly used for the determination of the calorific value of combustible materials such as coal, petroleum, chemical, food, wood, explosives, etc., and the corresponding high calorific value and low calorific value are calculated while measuring the calorific value of the cartridge.

3.It adopts advanced touch LCD screen. The overall installation method ensures the firmness of the touch screen.

4.It adopts infrared technology and CRT display material to make the touch screen more durable. The multi-layer composite film covering ensures the best color distortion degree, reflectivity and clarity. It has highly sensitive with high positioning accuracy. The wear resistance is as high as 90% in the infested area. The service life is up to 10 years.

5.It adopts English display, and can be directly operated without external computer.More than 1000 data can be stored and temperature rise curve can be displayed.

6.It adopts advanced single-chip system and fully automatic operation. All you need to do is to weigh, load and fill oxygen. The instrument can automatically finish water injection, stirring, ignition, results print out and drainage, etc.

7.It has reasonable structure, excellent production, reliable performance and low failure rate, accurate test result. It adopts unique cooling correction system to ensure long-term stability of the instrument performance.

8.It is controlled by microcomputer. Coal quality report can be provided.Human-computer interaction is available, which is easy to learn. The water injection and drainage is automatic, no need to adjust water temperature. All you need to do is to put the oxygen bomb into the cylinder. The instrument will complete all the test process automatically.

9.The structure is accurate, and the unique cooling correction system is adopted to ensure the long time stability of the performance.

10.The advanced electronic refrigeration process is completely immune to changes in ambient temperature, ensuring that the temperature difference between the inner and outer cylinders of the instrument meets the requirements of the national standard. Long time continuous work is available.

11.The vacuum inner cylinder is made of stainless steel. The mixing system adopts imported motors from Germany.

12.It has fast test speed, and the test period is ≤8min (fast method) ≤15min. The repeatability and reproducibility of the calorific value test is better than the requirements of national standard GB/T384 Petroleum Products Calorific Value Method, and GB/T213-2008 The Coal Calorific Value Test Method and ASTM D240

13.This product has excellent performance and reliability even in harsh environments.

14.It has highly automatic. It can complete the whole test process by automatically using the amount of water in the built-in fixed container and automatically control the temperature difference between the inner and outer barrels.

15. It has rich data processing function. The historical test data, current day data and parallel sample data, etc. can be easily queried.
