ZDHW-8D Fully Automatic Chinese Character Calorimeter
1、 Purpose:
This instrument is a multifunctional calorimeter developed using a single-chip microcomputer, mainly used for measuring the heat generation of solid and liquid combustibles such as coal, petroleum, food, wood, explosives, and other substances.
This instrument is a new type of energy-saving analysis instrument developed by our company. The carefully designed calculation program greatly improves the measurement accuracy. It adopts a liquid crystal display, fully displayed in Chinese, and is easy to operate. It can achieve full automatic control of the measurement process, automatic water addition and drainage, automatic ignition, stirring, calculation, and printing of the calorific value of the measured substance. The test results are clear at a glance. It is an ideal equipment developed for the production and research of combustible materials in enterprises and scientific research and military departments of colleges and universities.
2、 Technical features
Compared with similar machines, this instrument has the following characteristics:
1. This machine is composed of high-end single chips, with a simple structure, reliable performance, and strong anti-interference ability.
2. It can automatically add water, drain water, stir, ignite, collect temperature, calculate, calibrate, and print. The experimental process is fully automated, avoiding human errors and greatly improving accuracy and precision.
3. The automatic cooling calibration of the experiment has a relaxed requirement for environmental temperature, which not only improves the accuracy of the experiment but also ensures the stability of the instrument during long-term operation.
4. After the experiment, the high and low heat generation can be converted for printing, which is more in line with general conventional experiments.
5. Full Chinese display, easy to operate.
3、 Main technical specifications:
1. Heat capacity: approximately 10500J/K
2. Oxygen bomb: capacity 300ml/oxygenation pressure 2.8~3.0MPa/pressure resistance - water pressure 20MPa/weight 2.5Kg/external dimensions - Φ 86.2 × 181mm
