Electrochemical DrägerSensor® - Draeger

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 ...
