Features of Microcomputer Total Self Momentum Thermometer:
● Is mainly composed of constant temperature calorimetry system and single chip microcomputer control system, which is a highly automatic heat measuring instrument controlled by single chip microcomputer system and can process data;
● This instrument is mainly used for the determination of calorific value of combustible substances such as coal, petroleum, chemical industry, food, wood and explosives.
● Use American advanced technology touch LCD screen, integral installation method to ensure the fastness of touch screen.
● Infrared technology, material selection CRT display materials to make the touch screen more durable. Multi-layer composite film cover to ensure color distortion, reflection and clarity to the best state, sensitive induction, high positioning accuracy, effective area up to 90% wear resistance, life can be up to 10 years.
● Chinese character display, do not need external computer, can operate directly. Can store more than 1000 data, showing the heating curve.
Using the advanced single-chip microcomputer system, the operation is fully automatic, the manual needs to do only weighing, loading and oxygenation, the instrument automatically completes the quantitative water injection, automatic stirring, ignition, output printing results, drainage and other work.
● Structure is reasonable, production is excellent, performance is reliable, failure rate is low. The results are accurate and the unique cooling correction system is adopted to ensure the stability of the instrument for a long time.
● Controlled by a microcomputer, can provide coal quality reports, human-computer interaction, that is, learning. Automatic water injection, drainage, do not need to adjust the water temperature, only need to install oxygen bomb into the tube, the instrument automatically complete all the testing work.
Accurate
● Structure, unique cooling correction system to ensure long-term stability of instrument performance. The advanced electronic refrigeration technology is completely unaffected by the change of ambient temperature to ensure that the temperature difference between the inner and outer cylinders of the instrument meets the requirements of national standard. Can work for a long time.
Stainless steel vacuum inner cylinder. The mixing system adopts German original imported motor.
● Test speed is fast, the test period ≤8 min( fast method)≤15 min, the repeatability and reproducibility of calorific test are better than those of national standard GB/T384《 petroleum product calorific value determination method and coal calorific value determination method.
The product has good performance and reliability even in harsh environments.
High degree of
● Automation, automatic use of the built-in container bucket water quantity, automatic control of the instrument inside and outside the bucket water temperature difference, automatic completion of the whole process of the test.
● Data processing is rich, users can easily query historical test data, day data, parallel sample data and so on.
