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
