Specifications
System Measurement SpecificationsTable 1:
Specification Description
Net O2 range 0 - 23%
Repeatability 0.1% of O2 or 1.0% of reading, whichever is lower
Lowest detectable limit 0.05% O
Process temperature effect Less than 0.3% O2 from 77 to 1292 °F (25 to 700 °C)
System speed of response to calibration gas Initial response in less than 3 seconds, T90 in 10 seconds. Re-
sponse to process gas changes will vary depending on process
gas velocity and particulate loading of the diffuser.

Installation specifications
ProbeTable 5:
Specification Description
Probe mounting range Vertical or horizontal: 2-in. 150# (4.75 in. (121 mm) bolt circle) and DIN145
Note
Flanges are flat-faced and for mounting only. Flanges are not pressure-rated. A 2.5-in.
diameter hole in the process is required.
Many adapter flanges are available to mate to existing flanges.
Reference air No instrument air required. Ambient air diffuses into the probe passively. Ensure that
ambient air is fresh (20.95% O2).
Calibration Semi-automatic manual gas switching. New calibration values are calculated in the
remote electronics.
Cal gases 0.4% and 8% O2, balance N2 recommended. Instrument air may be used as a high cal
gas, but is not recommended. 100% nitrogen cannot be used as a low cal gas.
