ZDHW-9A

● ZDHW-9A High-Precision Microcomputer Automatic Calorimeter Performance Features:

■ Utilizes intelligent refrigeration technology to automatically adjust the temperature of the 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, it can convert and print data including bomb calorific value, gross calorific value, and net calorific value.

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

■ The microcomputer calorimeter operates on Windows 98 and above operating systems, with full Chinese language prompts and interactive user interface. It is easy to learn and use, allowing tests to be completed by following the prompts.
