I.Overview

This instrument is used to measure the calorific value of solid, liquid and other combustible materials (coal, petroleum food, wood, biomass).

The instrument is a new type of energy-saving analysis instrument developed by our company. The calculation program carefully compiled improves the measurement accuracy greatly. Color and touch display,good user interface. The measurement process is automatically controlled to reduce human error. Print cartridge, dry base high position

The results are clear and clear.

II.Technical features

1. It has the advantages of simple structure, reliable performance and strong anti-interference ability.

2. The test steps such as flushing, discharging, water level setting, mixing, ignition, temperature recovery, correction, calculation and printing are completed automatically to avoid human error and improve the accuracy and precision.

3. 3The unique calibration technology makes the requirements of the instrument to the environment relatively relaxed. The accuracy of the test is improved while the stability of the long-term operation is ensured.

III.Working principle

0.9-1.1g of the substance to be tested is put into a heat crucible (heat-resistant and anti-corrosion), and the crucible is placed in an oxygen bomb added with 2.8-3.2mpa oxygen, and put into the inner cylinder of the calorimeter. The inner cylinder is added with quantitative distilled water. The heat output of the combustible can be calculated according to the rise of water temperature and the heat capacity of the calorimetry system.
