High Quality Oxygen Bomb Calorimeter
Working principle:
Using advanced single-chip system, the operation is fully automated. All the labor needs to do is to weigh, load and oxygenate. The instrument automatically completes the quantitative water injection, automatic mixing, ignition, output printing results, drainage, etc.
In the calorimetric system of the calorimeter, in addition to the heat absorbed by the water, the oxygen bomb, the inner cylinder, the thermometer and the agitator absorb heat, and the respective heat absorption conditions are different. Various factors are complicated, and it is impossible to rely on simple Mathematical calculations can only use the reference of known calorific value, such as benzoic acid, to actually calibrate the heat absorbed by the calorimeter system for every 1 °C increase, that is, to calibrate the calorimeter's heat capacity.
Features:
With the unique tracking and correction technology, the requirements of the instrument on the environment are relatively loose, which not only improves the accuracy of the test, but also ensures the stability of long-term operation.
The inner cylinder adopts the electric stirring of flaky paddles and the fusible ignition mode of cotton thread, which has high reliability and convenient operation.
The time temperature curve is drawn in the experimental process, which is helpful to observe the experimental process.
The operation is fully automatic. All the manual work is weighing, loading and oxygen filling. The instrument automatically completes the work of quantitative water injection, automatic mixing, ignition, output of printing results, drainage, etc.
Single pump displacement type water injection and drainage can eliminate the problem that the drainage pump of the original double pump type is easy to block, and the water injection time is not adjusted from then on.
