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 Oxygen and Toxic Gas Detection
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

Difference between oxygen and toxic gas detection
Oxygen and toxic gas detection serve two different safety functions:
- Oxygen detection monitors the concentration of oxygen in the air to ensure levels remain safe for breathing and to prevent oxygen-deficient or oxygen-enriched environments, which can lead to asphyxiation or increased fire risk.
- Toxic gas detection identifies the presence of harmful gases, such as CO, H₂S, NH₃, Cl₂, SO₂, or VOCs, that can pose immediate or long-term health hazards even at low concentrations.
The right sensor type depends on the target gas, detection range, environmental conditions, and response-time requirements. Contact us for assistance choosing the right detector(s) for your facility.
Toxic gas detector price:
Gas detector pricing varies based on it's technology and features. Basic single-gas portable units may start at a lower cost, while fixed detectors with advanced sensor technology, data logging, remote monitoring, and integration into larger safety systems typically fall into a higher price range. Complex applications, such as multi-gas monitoring or continuous industrial process monitoring, can influence pricing as well. Ultimately, the cost reflects the sensor type, accuracy, and durability needed to maintain a safe and compliant work environment.
