GD-ISO1716 Bomb Calorimeter

GD-ISO1716 Bomb Calorimeter

Bomb calorimeter is also named heat of combustion tester.  It meets the technical indicators and requirements specified in the GB/T 14402-2007 “Determination of Combustion Performance of Building Materials and Products - Determination of Combustion Calorific Value”. It is suitable for the test of combustion calorific value of building materials. Its equivalent standard is ISO 1716.

Bomb calorimeter is used to determine the gross heat of combustion of products at constant volume. The test method specified in this standard is used to test the absolute calorific value of the combustion of the test article, independent of the form of the article.

The refrigerator is improved on the basis of I, and the electronic refrigeration is replaced by the compressor refrigeration, and the temperature control accuracy is high. 

It overcomes the disadvantages of electronic refrigeration that the cooling speed is slow and the temperature is difficult to keep constant during the experiment, so that the water temperature of the host during the experiment is always constant at the required set temperature.
