    The CWD2005 BASIC is the standard combustion calorimeter for online determination of the Wobbe Index and specific density. The Wobbe Index and the specific density are measured directly, calorific value and CARI are calculated from these values.
    It is suitable for all combustible gases - even low calorific gases can be measured with a support gas supply. Additionally, the CWD provides optionally a measuring range switch to measure huge measuring ranges. Further, due to the very robust measuring system it is possible to measure heavily contaminated gases such as coke gas and blast furnace gas without significant increased maintenance requirements.
