Performance Data:
1. Temperature Dependency
The following figure illustrates the typical effect of temperature on the output signal of the ECO-dura .The sensor was calibrated at 20 ℃ and 40%RH (Io).
3. Humidity Dependency
The following figure illustrates the typical effect of humidity on the output signal of the ECO-dura .The sensor was calibrated at 20 ℃ and 40%Rh.
3. High Concentration CO overload
In EN50291, the sensor must be endured 5000 ppm CO impact and must be recoverd in 1 hour by itself. The following graph shows good performance of ECO-dura sensors.
