Complete automatic calorimeter, automaticly stir, ignite, display status of process, alarm and print the result.

GC106 Calorimeter is new developed model based on ZDHW-5 Calorimeter.

General Introduction of Water Equivalent Of Calorimeter

Calorimeter calorimeter system, in addition to the water absorbs heat, the oxygen bomb, inner tube, thermometer and stirrer, and this will absorb heat, and absorbing their situation is different, more complex variety of factors, it is impossible to rely on a simple mathematical calculations to obtain, but to use the reference material of known calorific value such as benzoic acid to the actual calibration of the system temperature is increased by the amount of heat to be absorbed heat 1 ℃, which is calibrated out of the heat capacity of the calorimeter.

 

 

Under High Pressure Oxygen Condition:

Put samples in hot-corrosion-resistant metal crucible.     

Put this crucible in oxygen bomb and seal it.     

Charge oxygen in the bomb until the pressure reach 3.0Mpa     

Put oxygen bomb in and turn on the calorimeter, burn the sample.

The heat will pass to the water in cylinder.

Calorimeter can calculate the calorific value of samples according to measure the water temperature, cylinder and bomb.

 

 

Features of GC106

The instrument is the use of monolithic microcomputer development of multifunctional heat measuring instruments, mainly for solid and liquid fuel, such as coal, oil, food, wood, garbage, coal, coke and other substances - Determination of calorific value. The system runs on Windows98 and above systems, into the machine interaction, that is used to. The software uses an object-oriented programming method, modular management technology, multi-task operation, the use of advanced serial communication technology, integrated system control and data management, good compatibility, ease of maintenance, to overcome the drawbacks of the computer interface board quit, with a wide range of adaptability, and effective use of scientific algorithms, data, high precision, stable and reliable system.

 

Working Principle of Water Equivalent Of Calorimeter

Same as ZDHW-5 calorimeter, it is composed of shell, outer cylinder, inner cylinder, stirrer, oxygen bomb and so on. Outer cylinder is made of double shell stainless steel, the stirrer can adjust water temperature. There is also water inlet and outlet to adjust the water temperature and water level.
