ZDHW-8000 microcomputer automatic calorimeter 
 Scope 
 For electricity, coal, metallurgy, petrochemical, coal, environmental protection, cement, paper, geological exploration, food, feed, etc. Determination of the calorific value of combustible material. 
 Features 
 ① user-friendly design: the experiment computer program control, automatically calculate the cartridge, high, low heat, and after the experiment can be modified at any time sulfur, hydrogen, moisture, water and other experimental data analysis to obtain the corresponding cartridge, high , low heat, heat with sulfur, hydrogen, full of water, of water and other experiments at the same time, greatly facilitate the work of laboratory technicians 
 ② adaptability: to lower the working environment, incubators Chinese character display and working status of the host water tank temperature, tank temperature monitoring host microcontroller program, the use of refrigeration refrigeration compressor, the instrument can be used in indoor normal environment 
 ③ stability: TYZH-II the use of incubators, the instrument more than 24 hours of continuous change and the host water, actually reached the calorimeter temperature requirements to ensure continuous stability of the experimental results 
 ④ Intelligent Design: Experimental Automation: water, drainage, fire, computing, preservation process done automatically by the program 
 Automatic thermostat: Just turn on power to the thermostat, temperature control, refrigeration, water circulation in the process of automatically
