In industries ranging from coal mining and metallurgy to petrochemicals, power generation, and cement production, accurate measurement of fuel calorific value is critical—it directly impacts energy efficiency, cost control, and product quality. The ZDHW-600D Microcomputer-Automatic Calorimeter emerges as a reliable solution for this demand, engineered to meet both national and international standards. It fully complies with China’s GB/T213 (Determination of Calorific Value of Coal), GB/T384 (Determination of Calorific Value of Petroleum Products), JF/T1005 (Determination of Calorific Value of Cement Black Raw Meal), as well as global benchmarks like ASTM-D5865 (Standard Test Method for Gross Calorific Value of Coal and Coke), GB/T30727 (Determination of Calorific Value of Solid Biomass Fuels), and ISO 1928 (Solid Mineral Fuels—Determination of Gross Calorific Value by Bomb Calorimetry and Calculation of Net Calorific Value). Designed for quality inspection centers, refineries, power plants, and research institutions worldwide, this instrument redefines efficiency and accuracy in calorific value testing for solid and liquid fuels—including coal, coke, gangue, raw bricks, petroleum, and more.
The ZDHW-600D’s core advantage lies in its full automation, driven by a high-performance single-chip microcomputer control system. Once activated, the instrument autonomously completes all key testing steps: water filling, quantitative water control, stirring, water temperature adjustment, ignition, ignition success verification, temperature collection, data calculation, and result calibration. Human intervention is minimized to only three simple tasks: sample weighing, oxygen bomb loading, and oxygen charging. This not only drastically reduces labor intensity but also eliminates human errors—ensuring consistent, high-precision results even in high-volume testing scenarios.
User-friendliness is another standout feature. The instrument adopts a Chinese menu-based operation interface, paired with a 10-inch LCD screen that provides clear, step-by-step prompts. Technicians can initiate and monitor the entire test process with just a few taps, even with limited prior experience. For labs seeking advanced connectivity, the ZDHW-600D offers an optional USB port and compatibility with Windows operating systems, enabling seamless microcomputer control, data export, and integration with laboratory information management systems (LIMS)—adapting to diverse workflow needs.
Precision and stability are embedded in every detail of the ZDHW-600D. Its technical specifications reflect industry-leading performance: a heat capacity of approximately 10,500 J/K, temperature resolution of 0.0001°C, and calorific value detection accuracy of 0.1% (tested with benzoic acid)—ensuring results meet the strictest quality control requirements. The instrument completes a single test in about 15 minutes, balancing speed and accuracy for time-sensitive operations. It also features a large outer water jacket (40L) and inner water jacket (approximately 2.3L) to maintain stable temperature conditions, while a 24V ignition system (with a 5-minute ignition duration) guarantees reliable ignition without safety risks.
Durability and data security further enhance the ZDHW-600D’s value. Its robust structure and strong anti-interference capability ensure stable operation even in harsh industrial environments, with a low failure rate for long-term use. Critical parameters like system constants and test results are stored permanently—they remain intact even after power-off, allowing easy access to historical data, daily test records, and parallel sample data for trend analysis or regulatory audits. The instrument operates on AC 220V ±10% 50Hz power with a power consumption of less than 300W, making it energy-efficient and suitable for global voltage standards.
Whether you’re a coal-fired power plant optimizing fuel efficiency, a petrochemical lab verifying petroleum calorific value, or a cement manufacturer testing raw material heat output, the ZDHW-600D Microcomputer-Automatic Calorimeter combines global compliance, intelligent automation, and precise performance to meet your most demanding needs. It’s not just an instrument—it’s a strategic tool for enhancing operational efficiency and upholding quality across global markets.
