Air demand/Wobbe index analyzer
ATEX | CGA100 TECORA

Developped by GAZ DE FRANCE, the COMBUMATIC is designed to monitor the quality of Natural gas by determination of comburity or Wobbe index.
This parameter is very usefull when the change of natural gas composition can upset the process.
The instrument is based on an air/gas blender, a catalytic combustion chamber where is burnt the air/gas sample and a cell to measure the oxygen remaining after combustion.
A programmable controller receives all measured values and safety status and calculates the comburity and Wobbe index. This controller is also able to initiate automatic calibration cycles with malfunction detection related to the calibration.
