JCBZNLR-2013 Petroleum Product Calorific Value Tester

Category:

The instrument complies with the GB/T 384‑1981 standard for determining the calorific value of petroleum products. It employs a modular 24‑bit AD temperature‑acquisition circuit, ensuring temperature measurement stability to one ten‑thousandth of a degree. An embedded ARM processor serves as the main control unit, paired with a 7‑inch Android operating system, enabling straightforward and intuitive human–machine interaction. Leveraging the powerful data‑processing capabilities and exceptional scalability of computers, the instrument delivers comprehensive functionality, making historical data retrieval and printing both simple and efficient, while also paving the way for future device networking and data sharing. It incorporates virtually all the functions of earlier microcomputer calorimeters based on the “PC + controller” architecture, yet offers reliability that far surpasses their limitations.

Product Details

　　 Features:

　　The instrument complies with the GB/T 384‑1981 standard for determining the calorific value of petroleum products. It employs a modular 24‑bit AD temperature‑acquisition circuit, ensuring temperature measurement stability to one ten‑thousandth of a degree. An embedded ARM processor serves as the main control chip, paired with a 7‑inch Android interface, enabling simple and intuitive human–machine interaction. Leveraging the powerful data‑processing capabilities and exceptional scalability of computers, the instrument delivers comprehensive functionality, making historical data retrieval and printing straightforward while paving the way for future device networking and data sharing. It offers nearly all the features of conventional microcomputer calorimeters based on the “PC + controller” architecture, combined with unparalleled reliability.

　　Real-time cooling correction relaxes environmental temperature requirements, enhancing experimental accuracy while ensuring long-term instrument stability. Sulfur, hydrogen, and moisture data can be entered after the experiment is completed and automatically converted into higher and lower heating values, better aligning with standard laboratory procedures. The entire experimental workflow—water addition, drainage, stirring, ignition, temperature measurement, calculation, calibration, and printing—is fully automated, eliminating human error and significantly improving both accuracy and precision.
