  • The embedded system is composed of intelligent MCU, with simple structure, reliable performance, and strong anti-interference ability.
    2. Test steps such as water discharge, water level setting, mixing, ignition, temperature collection, calibration, calculation, printing, etc. are automatically completed, avoiding human error, and improving accuracy and precision.
    3. Support two ignition methods: ignition wire and cotton thread
    The casing of the chassis has a water level indicator line that allows you to observe whether the inner cylinder is short of water at any time.
    5. The ignition voltage and current can be observed outside the chassis at any time.
    6. There is no need to weigh or adjust the water temperature, which reduces the working intensity and improves the measurement accuracy.
    7. The 7-inch color LCD screen is used and installed integrally to ensure the firmness of the LCD screen. It can be operated directly without an external computer.
    8. The operation buttons adopt automatic touch type buttons, which make the operation simpler, more flexible, and more efficient;
    9. It has a voice broadcast function, and during the experiment, each button will be operated with a voice prompt; (The beginning and end of the experiment, etc.) will be prompted by voice;
    10. The advanced imported single-chip microcomputer system is used to control the instrument, and the original imported mixing motor is used. The mixing speed is stable, the performance is reliable, and the anti-interference ability is strong.
    Using unique calibration technology, the instrument has relatively loose environmental requirements, which improves test accuracy while ensuring stability during long-term operation.
    12. Under the prompt of the full Chinese menu type operation interface, the user only needs to load the oxygen bomb to complete the entire experimental process. Intuitive, friendly, easy to learn, and easy to use. The experimental results are clear at a glance, and the operation is simpler and more user-friendly.
    13. The instrument can automatically display the ignition voltage and current, and has an automatic diagnosis function.
    14. This instrument can measure substances with lower calorific value and automatically calculate the calorific value by inputting the calorific value and weight of the additive.
    15. Automatic control of the measurement process to reduce human error. Print cartridge, dry base high level
    16. High analytical basis, low analytical basis, and calorific value as received.

  • Microcomputer automatic calorimeter is suitable for measuring coal, coke in power industry, coal, waste calorific value, biomass fuel calorific value, petroleum, metallurgy, petrochemical, quality inspection, environmental protection, cement, papermaking, geological survey, scientific research institutes and other industrial sectors. The calorific value of flammables such as petroleum, cement, raw materials of cement, bricks and other solids or liquids is in line with the requirements of the national standard GB/T213-2008 "Measuring calorific value of coal". High-precision microcomputer automatic calorimeter is the main instrument of coal quality laboratory.
