Product Description

GDY-1A+ Digital Bomb Calorimeter for determination of caloric values of samples in liquid or solid

Product Description

Preface:

1. For bomb calorimeter, the reaction takes place in a sealed metal container, which is placed in the water in an insulated container. Heat flow from the reaction crosses the walls of the sealed container to the water. The temperature difference of the water is measured, just as it was for a coffee cup calorimeter. Analysis of the heat flow is a bit more complex than it was for the coffee cup calorimeter because the heat flow into the metal parts of the calorimeter must be taken into account.

q_reaction = - (q_water + q_bomb)

where q_water = 4.18 J/(g·°C) x m_water x Δt

2. The bomb has a fixed mass and specific heat. The mass of the bomb multiplied by its specific heat is sometimes termed the calorimeter constant, denoted by the symbol C with units of joules per degree Celsius. The calorimeter constant is determined experimentally and will vary from one calorimeter to the next. 

q_bomb = C x Δt

3. Once the calorimeter constant is known, calculating heat flow is a simple matter. The pressure within a bomb calorimeter often changes during a reaction, so the heat flow may not be equal in magnitude to the enthalpy change.


Main Features:

1. The Digital Bomb Calorimeter adopts technology of single chip machine, LCD screen, high accuracy temperature sensor and high performance A/D conversion device. It is a highly intelligent instrument.

2. The test procedure is fully automatic. After placing the sample and inputting the right parameters, the instrument will finish all the procedures without manual interference. It will print the test data directly after test is over.

3. This Digital Bomb Calorimeter adopts sealed oxygen bomb. The whole structure adopts stainless steel material.The strength is enough to resist 20MPa hydrostatic test under room temperature.

4. The inner water container is made of stainless steel and the section likes as a pear.Its water volume is 3000g and with electric stirrer to make sure the uniform temperature in water bath.

5. The external water jacket is a double container.It will be filled fully with water when testing,and the stirrer in the water jacket will work to ensure the uniform temperature and create the constant temperature condition for test requirement.
