The electrochemical are designed to provide a reliable und stable measurement function over a long period of time. The use of resistant plastics, such as PTFE, and the purest catalysts make this possible. Additionally, a huge electrolytic reservoir and large electrode areas provide sufficient reserves for a long lifetime. The construction of the DrägerSensors offers you long stability and a low age-related drift.

All DrägerSensors are factory calibrated with the target gas. These values are saved in the internal, electronic memory. You can use the sensors in the field immediately. For some sensors other tagret gases can be selected from the internal gas library.

All sensors have an internal temperature sensor. Between -40°C and +65°C, the temperature influence is compensated for zero and sensitivity. The patented internal pressure compensation balances adverse ambient conditions, such as humidity changes or barometric variation. Due to this fact, you can use the sensors even in high or low pressure. For some sensors you can reduce the disturbing influence of cross-sensitivities by combining selective filters.

The Dräger SensorAlive is an electrochemical sensor with an integrated gas generator. The gas generator enables daily automatic sensor testing with hydrogen sulfide (H2S) as the test gas. It also alerts when the sensor inlet is clogged, preventing gas from reaching the sensor. Daily bump tests help to improve the safety of your gas detection system and allow for extended preventive maintenance intervals. Find out more
