DrägerSensor EC Electrochemical Sensors
Faster response – higher accuracy – greater stability – longer life. Dräger electrochemical sensors offer all these benefits. The robust and long-life sensors are used for the selective measurement of the smallest concentrations of toxic gases and oxygen in ambient air.
Product features
- Long life time
- The use of resistant plastics, such as TEFLON, and the purest catalysts make it possible to achieve a long, wear-free measurement function over long periods. A patented internal pressure compensation mechanism compensates adverse environmental influences from changes in humidity, temperature expansion and weather-related variations in air pressure. A large electrolytic reservoir and large electrode areas provide sufficient reserves for a long life time, even in industrial environments.
- Ready for use immediately
- All sensors are factory calibrated, and these values are saved in the internal, electronic memory. This means that sensors in the field can be used immediately. The high-quality technical construction guarantees a long stability and low, age-related drift.
- Comprehensive range of applications
- All sensors have an internal temperature sensor. Between -40°C and +65°C, the temperature influence is compensated to zero, and the sensitivity is automatically adjusted. The internal pressure compensation allows the transmitters to be used during extreme low pressure, and high atmospheric pressure. In combination with exchangeable, selective filters, it is possible to reduce the influence of disruptive cross-sensitivities.
- Advanced sensor technology
-
- It is possible to choose between oxygen sensors for partial pressure measurement or volume percent measurement.
- Acid gas sensor AC with unlimited life time, due to refillable electrolyte.
- Sensors with organic electrolyte for detection limits in lower ppb range.

Literature
List of detectable gases and vapours.
For over 70 years, Dräger has been one of the technology leaders in gas detection.
When there’s danger in the air ... this can quickly pose a high risk to humans, the environment, and all types of property and systems. Recognize the threat before it is too late.
Safety Instrumented Systems are used to reduce the risk for the protection of people, plants, and environment.
Explosion hazards mostly arise from flammable gases and vapours. Instead of avoiding their ignition by explosion protection measures it may be preferable to detect them before they become ignitable.
