Measurement and analysis of combustion gas is a common and necessary task that assists in fulfilling regulatory compliance requirements and attaining highest fuel efficiency levels. Gas analysis is also utilized in many processes for quality assurance, process control and other applications. In situ gas analyzers can target specific gas constituents and provide continuous streams of measurement data for single or multiple target gas components.

An in situ analyzer is a permanently installed instrument that resides right in the process. Its sensor is installed within the process gas stream. These devices, because of this locating, must be physically rugged and able to provide sufficient resistance to corrosion, heat, moisture and other environmental conditions found at a process facility. Additionally, some may require compliance with requirements for installation in a rated hazardous area. 

The benefits derived from overcoming the challenges of in situ location of the analyzer are substantial, especially when compared to the alternative of periodic gas sampling and laboratory analysis.
  • Direct, fast in-situ measurement directly in the process
  • No gas sampling, transport or conditioning
  • Up to eight measuring components at the same time, plus process temperature and pressure
  • Numerous independent measuring ranges with consistent accuracy
  • Overpressure encapsulated design for ATEX Zones 1 and 2
