ZDHW-9B High-Precision Microcomputer Automatic Calorimeter

● Performance Characteristics of ZDHW-9B High-Precision Microcomputer Fully Automatic Calorimeter:

■ Utilizes intelligent refrigeration technology to automatically adjust the temperature of inner and outer cylinders, reducing the cooling correction coefficient for more accurate measurement results.

■ Complies with the national standard GB/T213-2008.

■ The microcomputer calorimeter retains all functions of the microcomputer system, allowing simultaneous operation of general software for other tasks. It can automatically calibrate the energy equivalent (heat capacity) of the calorimetric system and measure calorific value. By inputting data such as sulfur, moisture, and hydrogen content, it can convert and print data including bomb calorific value, gross calorific value, and net calorific value.

■ The inner cylinder of the calorimeter employs an electric stirrer with blade paddles, while the outer cylinder uses a submersible electric stirrer, ensuring more uniform and convenient stirring. The instrument adopts a fuse-type cotton thread ignition method.

■ The microcomputer calorimeter operates on Windows 98 and above operating systems, featuring full-process Chinese prompts and interactive interfaces. It is easy to learn and use, allowing users to complete tests by following the prompts.
