大型放熱系統– O2 / CO2
ISO 9705，IMO FTPC第10部分

大型和小型氧氣消耗量計使用相同的分析儀和氣體採樣設備對氧氣和CO / CO2測量進行定量分析。量熱計RIG的氧氣消耗量熱分析儀和氣體採樣設備（包括高容量泵和過濾裝置）位於一個單獨的外殼中，可以很容易地與A分離。透過雙重分析量熱儀功能，分析儀外殼可以同時用於錐形量熱儀（ISO 5660）和大量熱儀（ISO 9705）。

對於大規模測試，分析儀外殼與圓錐設備斷開連接，並可以輕鬆地在安裝的腳輪上移動到大型量熱儀的新位置，在此將其連接到大型量熱儀的電源和採樣線。

Large Scale Heat Release System – O2/CO2
ISO 9705, IMO FTPC PART 10

Large Scale and Small Scale Oxygen Depletion Calorimeters use the same Analyzers and gas sampling apparatus for the quantitative analysis of Oxygen and CO/CO2 measurements. The Calorimeter RIG houses the Oxygen Depletion Calorimetry Analyzers and gas sampling apparatus including high capacity pumps and filtration in a separate housing that can be easily detached from the A. By this Dual Analysis Calorimeter feature, the Analyzer housing can then be used for both the Cone Calorimeter (ISO 5660) and Large Calorimeter (ISO 9705).

For Large Scale testing, the Analyzer housing is de-coupled from the Cone apparatus and easily moved on the fitted casters to the new location of the Large Scale Calorimeter where it is coupled to power and sampling lines of the Large Calorimeter.

The RIG measures: –
Rate of heat release (kW/m2)
 Effective heat of combustion (MJ/kg)
 Time to ignition
 Smoke density
 CO production
 CO2 production
