Gas Analyzer


SICK offers a broad range of gas analyzers based on a variety of powerful measurement principles. With its in-situ and extractive measurement technology for equipping complete facilities, SICK can also provide solutions for a variety of systems and complex measurement tasks.

Gas transmitters

Gas Trasmitter

When it comes to creating gas analyzers that can serve as field instruments, gas transmitters are the logical next step. However, compared to the former, a gas transmitter requires barely any additional technical aids to perform the measurement task.

In many cases, there is no need for costly sampling and gas conditioning either.

In-situ gas analyzers

InSitu Gas

Real-time gas analysis directly within the process Innovative measurement technology that allows the devices to be mounted directly at the measurement site:

In-situ gas analyzers take measurements directly within the process under system conditions. These analyzers are primarily characterized by their minimal maintenance requirements and extremely short response times.

SICK’s in-situ gas analyzers are available in two different versions:

  • The cross-duct version for representative measurement results across the entire duct diameter
  • The measuring probe version, optimized for single-sided gas duct installation

Extractive gas analyzers

Extractive gas analyzers

SICK’s extractive gas analyzers can be used in a large number of applications. The extractive measurement technology extracts a partial gas flow from the gas duct, conditions the extracted gas and feeds it to an analyzer module under constant conditions.

All the measurement technology that SICK offers – from gas sampling and conditioning right through to the numerous analyzer modules – is perfectly tailored to the measurement task concerned.


SICK’s analyzer solutions provide forward-thinking concepts for measuring tasks in the fields of emission and process measurement technology. Typical fields of application include emission and process measurements in power plants, waste incineration plants, cement plants, and the chemical industry.

CEMS solutions


Tailored for measuring emissions.

SICK’s CEMS solutions are analyzer solutions that have been specifically designed for measuring emissions at power plants, industrial facilities, or on ships.

CEMS solutions can be used to measure pollutants and reference quantities and to perform data processing on the results in accordance with the relevant national or international legislation.

Process solutions

SICK Process

Forward-thinking solutions for process measurement technology.

Industrial processes and systems vary widely depending on the nature of the production method involved.

In turn, this means that the associated measurement tasks and process-related requirements differ a great deal as well.

SICK provides solutions and complete systems based on its extensive experience within the field of process measurement technology.
