ADAGE Vietnam, CWD2005 BASIC, UNION INSTRUMENTS CWD2005 BASIC, Đại lý chính hãng ADAGE Vietnam




Adage is an exclusive& authorized partner for M/s.Union Instruments GmbH in India. The Union make CV analysers are used to measure the calorific value for most of the gases in the industry. The analysers can be used in most of the applications which include Iron and steel , Bio gas ,  Oil & Gas ,  chemical industries, power plants, custody transfer measurementand many more. The analyser models are also available with ATEX certification suitable for Zone 1 & Zone 2 area classifications.

Product Overview

The CWD2005 device series (Calorimetry, Wobbe-Index und Specific Density) comprises versions of combustion calorimeters for direct and continuous determination of gas quality from the following measurands and operands:

  • Wobbe-lndex

  • Specific density

  • Heating and combustion values

  • Combustion Air Requirement (CARI) and air requirement, with integrated gas analysis

  • Energy quantity, with expanded system EMS2005.

​The Wobbe index and specific density are measured, and the heating value and combustion value are calculated from these measurements.When components for gas analysis are added to the CWD2005, the air requirement, or CARI, can also be determined from the analyzed gas composition.The operating principle of the CWD enables all combustible gas components to be detected, which allows it to be used even for gases with rapidly changing gas composition



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.
