YPRZ-3A touch screen oil fuel combustion heat value tester
This oil fuel combustion heat value tester meets the requirements of GB/T384 National Standard for Heating Value Inspection of Petroleum Products. It is used to test the heating value of various fuel oils, including petroleum, light oil, heavy oil, diesel, coal tar, asphalt, alcohol, chemical oil, paraffin oil, castor oil, orioil, tire oil, vegetable oil, fire oil, naphtha and other alcohol based fuels, as well as combustible solid or viscous liquid substances such as methanol fuel. It is also suitable for industries such as new energy, power, coal, metallurgy, petrochemicals, quality inspection, environmental protection, cement, papermaking, geological exploration, and research institutes to measure the heating value of various combustible materials such as biomass, new energy, building insulation materials, coal, petroleum, etc.
Functional features:
1. Adopting American embedded technology, a seven inch large color touch screen operation, and an integrated installation method to ensure the firmness of the touch screen.
2. The selection of CRT display materials makes the touch screen more durable. Multi layer composite film coverage ensures color distortion, reflectivity, and clarity, with sensitive sensing and accurate positioning, effectively appearing in areas with high wear resistance, Chinese character display, and direct operation without the need for an external computer.
3. Automatic water injection, no need to adjust the water temperature, just install the oxygen bomb and put it into the bucket, and the instrument can automatically complete all tests. Reasonable structure, humanized production, reliable performance, and low failure rate.
4. The Chinese menu style operation interface is intuitive, easy to learn and use, easy to operate, stable and reliable in performance, and adopts strong anti-interference ability through photoelectric isolation of the inner and outer cylinders. Adopting new foam insulation technology, the experimental process is not affected by external temperature.
5. Heat capacity repeatability uncertainty: ≤ 0.2%, precision<0.1%, temperature resolution 0.0001K.
