We are pleased to announce new specifications for the Figaro oxygen sensor SK-25F.

The major changes are as listed below:

1) Operating temperature range
Operating temperature range has been extended from 0 - 40˚C to -10 - 50˚C.

2) Atmospheric pressure range
Atmospheric pressure range has been extended from 1013hPa±10% to
1013hPa±20%.

3) Expected sensor life
It was confirmed that the sensor's life can be extended after confirming
that the sensor still keeps a good linear relationship between oxygen
concentration and sensor output voltage. It means that the sensor can be used approximately 3.0 years at 20˚C in normal air by periodical
recalibration.

As a result, expected sensor life at 20˚C in normal air has been extended as follows:

Old: Approx.. 2.5 years until 70% of original output
Current: Approx.. 3.0 years until 60% of original output

Please refer to the product information sheets available for each sensor on the Products page for further detail.
