Microcomputer high-precision fully automatic calorimeter

This instrument is the latest generation of intelligent fully automatic calorimeter, which meets and exceeds the requirements of the national standard GB/T 213-2008. It mainly consists of a constant temperature calorimeter system and computer control software, and is a highly automated heat measurement instrument that combines computer software with a microcontroller control system for 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. This system runs on the Windows XP system, with a user-friendly human-computer interaction interface that is easy to learn (does not support Windows 9)

2. Super large capacity water tank, automatic filling and drainage, no overflow, no need to adjust water temperature. Adopting scientifically effective algorithms, automatic cooling correction, and high data accuracy.

5. Automatically track the ambient temperature without the need to measure the outer bucket water temperature.

6. The system is stable and reliable, and can perform data processing after experiments.

7. Adopting serial communication technology, the failure rate is low. The usage environment requires a relaxed environment.

8. A brand new stainless steel ignition device reduces the probability of ignition failure.

9. 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.

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

6. 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 results, and drainage.
