High Quality Calorific Value Oxygen Bomb Calorimeter
Service conditions:
The test room shall be set in a separate room, and other test items shall not be carried out in the same room at the same time. It is better to face the north of the laboratory to avoid sunlight, otherwise the instrument should be placed in a place away from direct sunlight.
The room temperature should be kept relatively stable.
There should be no strong air convection in the room, so there should be no strong heat source, cold source, fan, etc. during the test, doors and windows should not be opened. If air conditioning has been installed in the laboratory, it is necessary to avoid direct air conditioning to the instrument.
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:
1. Adopts the fusible ignition mode of cotton thread, which has high reliability and convenient operation.
2. The time temperature curve is drawn in the experimental process, which is helpful to observe the experimental process.
3. The instrument automatically completes the work of quantitative water injection, automatic mixing, ignition, output of printing results, drainage, etc.
4. Single pump displacement type water injection, no need to adjust the water injection time.
