Elster® GasLab Q2 Real-time Natural Gas Analyzer

Brand: Honeywell Process Solutions
The GasLab Q2 is a gas quality analyser for natural gases, it is flame free, works quickly and continuously.

It determines the calorific value, Wobbe index and other parameters of the sample gas.

As opposed to the 'classic' gas chromatograph solution, the Honeywell Elster GasLab Q2 does not use carrier and mixed calibration gases or combustion air supply.

This translates into lower cost of ownership for the user.
Features
  • Determination of Main Gas Parameters: Calorific Value / Wobbe Index / Density / CO₂ Concentration / Methane Number etc.
  • Flameless, No Air or Carrier Gas Needed
  • Fast, Continuous Measurement
  • Easy Operation
  • Small Footprint: Low Investment and Maintenance Costs
  • Installation, Cost Saving Due to Easy Engineering and Commissioning
  • Less Downtime for Gas Turbine Installations
  • More Energy Efficient Turbine Control Because of Quick Response
  • Less Off-spec Gas for Blending Stations
  • Cleaner Burner Regulation
  • Optimized Emission of Processes
  • Better End Product Quality Control
