Our Impact

Save Energy


The integration of our gas measurement, monitoring, and analysis technologies into industrial processes promotes a more environmentally friendly economy and helps to reduce waste.

  • Our gas measurement technologies are essential for increasing energy efficiency and minimizing emissions in various industries. The instruments play a key role in monitoring process environments, which is critical not only for the efficiency of production processes but also for product quality.

  • In industries where accurate humidity control is important, dew-point sensors prevent excessive energy use for dehumidification, directly reducing energy consumption and the carbon footprint of our customers.

  • Oxygen analyzers or transmitters ensure optimal combustion efficiency and help reduce the release of greenhouse gases by enabling precise oxygen measurements in critical industrial processes.

  • Equipment maintenance is optimized through the use of our sensors and other gas monitoring products, increasing machine life, reducing the need for replacements and cutting emissions associated with the production of new equipment.

  • We also offer customized products and services that further support sustainability efforts.

Protect People and Process


Our advanced gas measurement products help protect people and make processes safer across numerous and highly diverse industries.

  • Explosion Prevention: In industries where explosive or flammable gases are present, our oxygen analyzers help maintain safety by monitoring oxygen levels. Keeping oxygen below a certain level can prevent the formation of explosive atmospheres. For instance, in chemical plants or fuel storage facilities, controlling the oxygen concentration is vital to prevent fires and explosions.

  • Corrosion Prevention: Our dew-point sensors are used to measure the temperature at which water vapor in the air condenses into liquid water. By monitoring and controlling humidity and dew point, these sensors help prevent corrosion in critical infrastructure, such as pipelines and storage tanks, especially in industries like oil and gas or water treatment. Corrosion can lead to leaks or structural failures, posing significant safety risks.

  • Environmental Monitoring: In pharmaceuticals, food, and semiconductor manufacturing, maintaining specific humidity levels is crucial for product quality and safety. High-precision humidity sensors and temperature monitoring systems ensure that the conditions in production and storage areas remain within the required specifications, preventing product spoilage or contamination that could be harmful to consumers.

  • Breathing Air Monitoring: In confined spaces, oxygen sensors are used to ensure that there is enough oxygen available for workers, protecting them from asphyxiation hazards. Our oxygen sensors are also essential in breathing apparatus for firefighters and divers, where they help ensure a safe breathing environment.

  • Process Safety: In many industrial processes, the precise control of humidity, oxygen, and other gases is critical for safety. For example, in power generation, controlling the moisture in fuel gases improves combustion efficiency and reduces the risk of equipment malfunction or accidents. Our oxygen analyzers in combustion processes help optimize the fuel-to-air ratio, preventing incomplete combustion and the production of dangerous byproducts like carbon monoxide.
