1. Signal output is measured in air at 25°C, sea level.
2. Accuracy full scale is calculated with constant pressure and temperature & proper calibration (90% O2 value on full scale range). Drastic temperature change can result in a maximum error of ± 10%.
3. Expected life is calculated when O2 is 20.9% @ 25°C, sea level
4. Southland Sensing warrants these sensors for the period noted above to be free from defects in materials and workmanship. Southland Sensing will not be held liable for sensors damaged due to customer neglect.
