● ZDHW-8A Microcomputer Fully Automatic Calorimeter Performance Features:
■ Utilizes intelligent refrigeration method, automatically adjusts inner and outer cylinder temperatures, reduces cooling correction factor to make measurement results more accurate.
■ Complies with the national standard GB/T213-2008.
■ The microcomputer calorimeter retains all functions of the microcomputer system, can run general software simultaneously for other tasks, and when the calorimeter measurement system is started, it can automatically calibrate the energy equivalent (heat capacity) of the calorimetric system and measure the calorific value. By inputting data such as sulfur, moisture, hydrogen, etc., it can convert and print data including bomb calorific value, gross calorific value, net calorific value, etc.
■ The calorimeter device uses electric stirring with blade paddles for the inner cylinder and submersible electric stirring for the outer cylinder, making stirring more uniform and convenient. The instrument employs a fuse-type cotton thread ignition method.
■ The microcomputer calorimeter operates on Windows 98 and above operating systems, with full-process Chinese prompts and human-computer interaction, easy to learn and use; simply follow the prompts to complete the test.
