ZDHW-800--Fully Automatic Calorimeter

This instrument is used for the determination of the calorific value of combustible materials such as solids and liquids (coal, petroleum products, food, wood).
This instrument is a new type of energy-saving analytical equipment developed by our company. A carefully designed calculation program significantly improves measurement accuracy. It features a color touch display with full Chinese language support and a user-friendly interface. The measurement process is automatically controlled to reduce human error. It prints the bomb calorific value, dry basis gross calorific value,
analysis basis gross calorific value, analysis basis net calorific value, and as-received basis calorific value, with clear and understandable results.
Technical Features:
1. Utilizes an intelligent MCU to form an embedded system, with a simple structure, reliable performance, and strong anti-interference capability.
2. Automatically completes experimental steps such as filling, discharging water, setting water level, stirring, ignition, temperature sampling, calibration, calculation, and printing, avoiding human error and improving accuracy and precision.
3. Employs calibration technology to make the instrument less demanding on the environment, enhancing test accuracy while ensuring long-term operational stability.
