 Notes:

1) When calibrated at both 0% and 30% of O2, accuracy in the range from 0-30% O2 shall be within ±1% full scale.

2) Sensors should be used under conditions where the air exchange is greater than 200~300ml/minute in order to obtain the response speed as specified in Table 1.

3) Life expectancy at 20? ± 1?C / 60 ± 5%RH in normal air (1013 ± 5hPa / 20.7% O2) is defined as the period until sensor output drops to 60% of original value.
