RESIDUAL OXYGEN MEASUREMENT
Our 9610CXc calorimeter Wobbe Index measurement is based on the analysis of the oxygen content in the flue gas after combustion of the sample. A continuous gas sample is mixed with dry air at a precisely maintained constant ration, which depends on the BTU range of the gas to be measured. The fuel air mixture is oxidized in a combustion furnace in the presence of a catalyst at 800°C, and the oxygen concentration of the combusted sample is measured by a zirconia oxide cell.

Wobbe measurement vs CARI measurement
Wobbe Index and CARI (Combustion Air Requirement Index) are two different measurements used in the natural gas industry to determine the quality of natural gas.
The Wobbe Index is a measure of the interchangeability of fuel gases and is defined as the heating value of the gas per unit volume divided by the square root of the specific gravity of the gas. The Wobbe Index is used to ensure that the natural gas being supplied to a customer meets the required heating value. Natural gas appliances are designed to operate within a specific Wobbe Index range, and if the gas supplied to an appliance is outside that range, it can result in inefficient combustion, incomplete combustion, and potentially dangerous conditions.
On the other hand, CARI is a measure of the combustion air requirement of natural gas. It is a method used to determine the amount of air required to completely combust a given volume of natural gas. The CARI measurement is important because incomplete combustion of natural gas can lead to the formation of carbon monoxide, which is a poisonous gas.
While the Wobbe Index and CARI both measure different properties of natural gas, they are related. If the Wobbe Index of natural gas is too high or too low, it can affect the CARI measurement, which can result in incomplete combustion of the gas. Therefore, it is important to ensure that the natural gas being supplied meets both the Wobbe Index and CARI requirements.
