Working Principle

The A2120 uses the oxygen bomb calorimeter method.

The testing principle is:

1. A prepared sample is placed into the oxygen bomb.
2. Pure oxygen is filled into the bomb under pressure.
3. The sample is ignited and completely burned.
4. The heat released increases the temperature of surrounding water.
5. The temperature change is measured with a high-precision temperature sensor.
6. The calorific value is calculated according to the temperature increase and heat capacity.

The method is widely used for petroleum products and coal calorific value analysis.
