Key Technology and Innovation of HW-8000 Automatic Isothermal Calorimeter
1. The patented oxygen bomb is required for the testing of pyrotechnics, which solves the technical problem that ordinary oxygen bombs cannot test pyrotechnics.
2. Take the lead in applying the principle of siphon to the water level balance to solve the defect of inaccurate positioning of the water level probe to ensure long-term stability of its heat capacity.
3. Solve the technical problem of temperature drift of the temperature control line part (main board) due to environmental temperature changes.
4, with a visual liquid level meter, always grasp the progress of adding water and long-term experimental work to replenish the instrument.
5. Connect with the electronic balance and automatically read the sample weight to avoid human input errors.
