Gas Warning

Stationary gas detection systems and mobile gas detectors

Industrie Gaswarnung: Gasmelder, Gaswarngeräte, CO2 Melder und mehr


Real-time warning with gas detectors

Gas detectors and area monitors reliably protect people from gas hazards.

Stationary gas detection systems and portable gas detectors are equipped with highly sensitive sensors. They measure hazardous substances even in the smallest concentrations and warn of potential hazards in good time. In this way, gas detection devices reliably protect people, the environment and the plant. With our range of sensor technologies, we cover a wide variety of application areas.



Our products

Stationary devices

Advantages of stationary gas measurement systems

  • Robust industrial designs
  • ATEX and SIL 2 designs
  • Use of 6 different sensor technologies
  • High-quality devices also for special applications


General information about stationary gas detectors

Our stationary gas detectors and gas detection systems are equipped with highly sensitive sensors. 6 different sensor technologies are used. These gas sensors communicate with evaluation devices, which activate the corresponding alarm devices via digital signals after the limit values are exceeded. The optical and acoustic alarm triggered in this way warns people in the vicinity and sets safety chains in motion. The gas sensors measure hazardous substances even in the smallest concentrations and warn of possible dangers in good time. In this way, they protect people, the environment and the plant.

Mobile devices

Advantages of portable gas detectors

  • Single gas and multi-gas detectors to detect one to seven gases through 15 different sensor options, including PID
  • also suitable for hazardous areas, ATEX
  • Area monitors with the longest run time - typically 7 days (168 hours)
  • DualSense® technology for increased worker safety
  • LENS™ wireless communication between area monitors and the gas monitors
  • iNet® Exchange subscription service for gas monitors for repair and replacement.
  • Management software iNet® Control for monitoring gases using a central dashboard
  • Live monitoring software iNet® Now with real-time alerts for gas hazards, panic and dead man situations
  • Wide selection of rental equipment


General information about mobile gas detectors

Our selection of single-gas and multi-gas portable gas detectors are suitable for monitoring one to seven gases. Up to 15 different flexible sensor options allow detection of combustible and toxic gases. The gas detectors allow extensive individual configurations. For example, individual messages can be created to relay safety information. These are shown on the display when the respective gas detector is switched on. LENS Wireless forwards panic and dead man alarms to other devices in a group. IP68 classification against dust and water ingress and a robust rubber casing guarantee long-lasting operation of the devices. We also offer a wide range of rental gas detection devices.
