Notes:

1) If used0%with30%If calibrated with two oxygen concentrations, the measurement range covers oxygen content0～30%whenKE-12F3LFwithKE-25LF/KE-25F3LFFull-scale accuracy is±1%，KE-50LFFull-scale accuracy is±2%. If used0%with100%If calibrated with two oxygen concentrations, the measurement range covers oxygen content0～100%whenKE-25F3LFMFull-scale accuracy is±1%。

2) To meet the response speed in the specification sheet, the sensor should be used under conditions where the air exchange rate is greater than200～300ml/under conditions of minutes.

3）20˚CNormal air (1013 hPa / 21%O2) The expected life refers to the period when the sensor output value drops to the initial value70%during this period.
