Oxygen and Toxic Gas Detection

In industrial environments the presence of toxic gases, vapors, or gas leaks that can affect ambient oxygen levels pose critical hazards. To address these risks Draeger offers a range of toxic gas detectors employing trusted detection principles such as electrochemical, catalytic infrared (IR), and open-path technology. Advanced detectors effectively detect over 400 different gases.

Toxic gas monitoring systems are equipped with versatile communication interfaces, including analogue and digital options such as 4-20 mA, HART(R), and fieldbus. Additionally, wireless gas transmitters enhance the completeness and flexibility of toxic gas monitoring systems.

Draeger’s patented electrochemical, catalytic, and infrared sensors outperform all other brands of sensors:

  • Longer life – typically 2-3 times the lifespan
  • Lower detection limits
  • Less cross-interference
  • No false alarms from changes in environmental conditions – temperature (most sensors are rated from -40 F to + 150f), humidity, pressure
