Vertical high-precision fully automatic calorimeter

This instrument is the latest generation of intelligent fully automatic calorimeter, which complies with GB/T 213-2008. It mainly consists of a constant temperature calorimeter system and a single-chip microcomputer control system, and is a highly automated heat measurement instrument that is automatically controlled by a single-chip microcomputer system and capable of data processing; This instrument is mainly used for measuring the heat generation of combustible substances such as coal, petroleum, chemical, food, wood, explosives, etc. At the same time as measuring the heat generation of the cartridge, it converts the corresponding high and low heat generation.

Its main characteristics and progressiveness are as follows

1. Adopting advanced single-chip microcomputer system and imported high-precision components to achieve high-precision temperature measurement. Combined with the complete and unique water injection and calorimeter system of the instrument, the system's thermal capacity can be automatically calibrated to determine the heat generation of the sample. By inputting data such as sulfur, moisture, hydrogen, etc., users can convert and print the results of the heat generation of the cartridge, high-level heat generation, low-level heat generation, etc., and print both card and joule units at the same time, making it convenient for users.

2. The inner cylinder adopts electric stirring with sheet-like blades; Adopting a fuse type cotton thread ignition method, it has high reliability and easy operation.

3. The instrument water tank and the water tank cover are all made of stainless steel and will never rust.

4. The ignition adopts a self recovery compound fuse, which can be self restored after melting and is maintenance free.

5. The operation is fully automated, with only weighing, loading, and oxygenation required manually. The instrument automatically completes tasks such as quantitative water injection, automatic mixing, ignition, output printing results, and drainage.

6. Adopting a well-designed oxygenation device, it is reliable and convenient to use.

7. The human-computer interaction interface is user-friendly, with a large Chinese character screen displaying time and experimental progress, making it easy to learn and use.
