I. Brief Introduction

Microcomputer automatic calorimeter is mainly composed of constant temperature bomb calorimeter and computer. It is a multifunctional automatic heat measuring instrument controlled by computer software and can process its data. The instrument has the characteristics of high measurement accuracy, easy operation, reliable use, beautiful appearance, etc. It is mainly used for the determination of caloric value of combustible substances such as coal, petroleum, chemical industry, food, wood and explosives.

1.Functional characteristics

1. Compact structure, exquisite material selection, excellent production, beautiful appearance.

2, the whole process is simple to operate, after the test is done without water directly cooling waiting for the start of the next experiment.

2, the use of compressor refrigeration and heating process, can continue to work for a long time.

3. Stainless steel vacuum inner cylinder.

4, the test speed is fast, the test period is ≤15min (GB/T213-2008).

5, thermal capacity stability < 0.2%, precision < 0.1%, temperature resolution 0.0001K.

6, the product has good performance and reliability even in harsh environments.

7, the repeatability and reproducibility of the heat test is better than the national standard GB/T213-2008 requirements.

8, high degree of automation, can realize the automatic lifting of oxygen bomb, automatic control of the amount of water in the barrel, automatic control of the temperature difference between the temperature of the barrel inside and outside the instrument, and automatically complete the whole process of the test. (Can be connected to the balance)

9, the use of Windows operating system, to achieve one machine multi-control, mutual testing does not affect each other, high software stability.

10, rich data processing functions, users can easily query historical test data, day data, parallel sample data, etc.
