1These typical values were obtained under the following conditions:

O2 Concentration:

20.95%

Sensor Temperature:

26.07°C

Current Output Range:

4-20mA

Range Endpoint, Low:

0%

Range Endpoint, High:

25%

Zero Offset Signal:

None

Pressure Compensation:

None

Near the end of the life of the sensor, the sensor voltage is typically 0.53V (disposable) or 0.48V (rechargeable). At temperatures (T) other than 25°C, multiply the voltages above by (1.025)exp(T-25).

3"-" is a minus sign displayed on the left of the display between AL 1 and AL 2.
